Complete Guide to Indian Traffic Rules

All vehicles in India must travel on the left side of the road. Wrong-side driving is a leading cause of head-on collision deaths.

Lane markings are legally binding instructions. A solid yellow centre line means no overtaking. A broken white line permits lane changes when safe.

You may overtake only from the right, only when the road ahead is clear, and never in prohibited zones. The vehicle being overtaken must make way.

Every driver must signal their intention to turn, change lanes, or stop — using indicators or prescribed hand signals. Failing to signal before a manoeuvre is a legal violation.

When an emergency vehicle is approaching with lights and siren active, every driver must immediately move aside to create a clear lane. The fine for blocking an ambulance is ₹10,000.

Drivers who cause an accident must stop, assist the injured, and report to police. The Good Samaritan Law protects bystanders who help accident victims from police harassment.

At a roundabout, vehicles already circulating inside have right of way. Enter by yielding at the give-way line, keep left, signal before exiting, and never stop inside the roundabout.

U-turns are permitted only at designated spots or where no "No U-Turn" sign is posted. You must check for oncoming and following traffic, signal, and complete the turn without obstructing others.

You may reverse only when it is safe, for the shortest distance necessary, and after checking that the path behind is clear. Reversing onto a main road from a side road is prohibited.

The two-second rule: pick a fixed point on the road and count at least 2 seconds between when the vehicle ahead passes it and when you pass it. In wet conditions, double it to 4 seconds. On highways at 100 km/h, 2 seconds = ~56 metres.

At intersections without traffic signals or signs, the vehicle approaching from the right has right of way. Vehicles on the main road have priority over side roads. At T-junctions, through-traffic has right of way.

Heavy vehicles have blind spots on all four sides, need more room to turn, and take much longer to stop. Never stay in a truck's blind spot, never undertake a turning truck, and always give extra following distance.

The default speed limit inside city/town limits in India is 50 km/h for cars and light motor vehicles. In school and hospital zones the limit may be 25–30 km/h.

Cars may travel at up to 100 km/h on undivided highways and 120 km/h on expressways. Trucks and buses are capped at 65–80 km/h. Motorcycles: 60 km/h on highways.

Near schools and hospitals: reduce speed to 25–30 km/h, do not use horn, and give way to school buses and ambulances. These are legally designated protection zones.

A valid driving licence for the vehicle class is mandatory at all times. Minimum age: 18 (LMV), 20 (transport). Driving without a licence: ₹5,000 fine + imprisonment.

All motor vehicles on public roads must be registered. The Registration Certificate (RC) must be carried at all times and must reflect the current owner's name.

Every motor vehicle on Indian roads must have at least third-party liability insurance. Driving uninsured: ₹2,000 fine and unlimited financial liability for accident victims.

A Pollution Under Control (PUC) certificate is mandatory for every vehicle and must be renewed periodically. Driving without one: ₹1,000 fine.

A learner's licence holder must always be accompanied by a person holding a permanent DL for the same vehicle class. An "L" plate must be displayed on the front and rear. Learners cannot drive on highways. The LL is valid for 6 months.

India is a signatory to the 1949 Geneva Convention. An International Driving Permit (IDP) issued in a convention country is valid in India for 1 year. Indians can obtain an IDP from their RTO for driving abroad. An IDP is not a standalone document — you must carry your original DL with it.

The Government of India recognises digital copies of DL, RC, insurance, and PUC stored in DigiLocker or mParivahan as legally equivalent to original documents. You do not need to carry physical documents if the digital versions are accessible.

All vehicle occupants — driver, front, and rear passengers — must wear seatbelts. Fine: ₹1,000 per person not wearing one. Rear seatbelts became mandatory in 2019.

Both the rider and pillion on any two-wheeler must wear an ISI-marked (BIS IS:4151) helmet with the strap fastened. Fine: ₹1,000 + 3-month licence suspension.

Children under 4 years / under 18 kg must be in an approved child restraint. Older children must wear seatbelts. Children must not travel on front seat of vehicle.

CMVR Rule 116 requires all motor vehicles to carry a first aid kit. For transport vehicles, the contents are specified: adhesive bandages, sterile gauze, antiseptic, scissors, triangular bandage, and a first aid manual. Private vehicles should carry a basic kit.

All buses carrying passengers, tankers carrying inflammable goods, and transport vehicles with more than 7 passengers must carry at least one 2 kg dry chemical powder fire extinguisher. Private vehicles are recommended but not mandated (yet).

All heavy motor vehicles (trucks, buses, trailers) must have retro-reflective tape on the rear (red and yellow, alternating stripes) and sides (yellow). The tape makes the vehicle visible from 150+ metres at night when headlights hit it.

At a red light: stop before the stop line. At amber: prepare to stop (do not accelerate). At green: proceed cautiously — green does not guarantee the road is clear.

At a signal or stop sign, vehicles must halt before (not on, not past) the painted stop line. Crossing into a box junction when the exit is blocked is an offence.

Drivers must stop for pedestrians at zebra crossings. Pedestrians have right of way at all designated crossings. Pedestrian fatalities at crossings are a major category of road deaths in India.

On one-way roads, all vehicles must travel in the direction shown by the arrow. Entry from the wrong end is dangerous driving. No overtaking from the left — overtake from the right (which is standard flow).

You must stop at a closed railway gate. At unmanned crossings, you must stop, look both ways, and verify no train is approaching before crossing. The penalty for ignoring a closed gate: ₹1,000 + 1 year imprisonment.

India's legal blood alcohol limit is 30 mg per 100 ml — one of the world's strictest. First offence: ₹10,000 + 6 months jail. Repeat: ₹15,000 + 2 years. A police breathalyser test is legally valid evidence.

Holding or using a mobile phone while driving is illegal and attracts a ₹5,000 fine. Hands-free calling in earphones is restricted in several states. Distraction from phones causes thousands of deaths per year.

Street racing and speed trials on public roads are criminal offences under Sec. 187 MV Act — ₹5,000 fine + 1 year imprisonment. Third parties killed by racing drivers face serious criminal charges.

Vehicles must not carry more passengers or goods than their registered capacity. Overloaded trucks face ₹20,000 + ₹2,000 per extra tonne. Overloaded buses with passenger deaths face criminal charges.

On a two-wheeler: no triple riding, both rider and pillion must wear ISI helmets, pillion must ride with both feet on the pegs, and no minor who cannot reach the foot pegs should be carried.

Section 185 MV Act covers driving under the influence of any drug in addition to alcohol. While India does not yet have widespread roadside drug testing, police can detain a driver suspected of drug impairment for medical examination. If drugs are found, NDPS Act charges may apply in addition to MV Act penalties.

Driving "in a manner so rash or negligent as to endanger human life" is a criminal offence under both the MV Act and IPC/BNS. It covers a wide range of dangerous behaviours — from stunt driving to ignoring traffic signs.

If you are involved in an accident, you are legally required to stop, render aid, report to the nearest police station, and provide your details. Fleeing the scene (hit-and-run) is a criminal offence with ₹2,00,000 compensation liability and up to 10 years imprisonment if death is caused.

No person under 18 may drive a motor vehicle on a public road. The 2019 MV Act amendment made the penalty severe: the guardian/owner of the vehicle faces ₹25,000 fine, 3 years imprisonment, and 12-month registration cancellation. The minor is dealt with under the Juvenile Justice Act.

Parking is prohibited within 15 metres of a fire hydrant, near bus stops, on yellow kerbs, opposite another parked vehicle (double parking), and at intersections. Tow trucks are authorised to impound illegally parked vehicles.

A vehicle stopped on a highway carriageway is one of the most dangerous situations in traffic. If you must stop, use the hard shoulder, activate hazard lights immediately, and place warning triangles 50–100 metres behind the vehicle.

Headlights are mandatory from 30 minutes before sunset to 30 minutes after sunrise. High beams must be dipped when oncoming vehicles are within 200 metres. Hazard lights are not a substitute for headlights.

In fog or heavy rain: use low-beam headlights (not high beam), reduce speed significantly, increase following distance to 3+ seconds, and use hazard lights only if stopped.

Horn use is prohibited in silence zones (hospitals, schools, courts). Multi-tone horns and air horns are illegal on private vehicles. The horn is a safety device — not a frustration-release tool.

Towing requires a proper tow bar or approved connection. The towed vehicle's brake lights must be functional. Maximum speed while towing: 25 km/h (rope) or as per the vehicle's registration. Rope-towing on highways is prohibited.

In rain: reduce speed by 20–30%, double your following distance, use low-beam headlights (not hazard lights), and avoid waterlogged roads where you cannot see the road surface. Aquaplaning (tyres losing contact with the road) begins at as low as 60 km/h on standing water.

In construction zones, temporary speed limits, lane diversions, and warning signs override normal road rules. You must slow down, follow temporary cones and barriers, and watch for workers, equipment, and uneven road surfaces.

On hill roads: the vehicle going uphill has right of way. Use engine braking (low gear) on descents. Sound your horn before blind curves. Never overtake on curves or near ridges. Park in gear with the handbrake engaged and wheels turned toward the hill.

India has a large number of stray cattle, dogs, and animal-drawn vehicles on its roads. The law requires you to slow down and navigate around animals with care. Aggressive honking may startle animals into unpredictable movement. In wildlife areas, animal crossing signs must be obeyed.

Only vehicles authorised by the government — ambulances, fire engines, police vehicles, and select VIP vehicles — may use sirens and coloured flasher lights. The Supreme Court (2013) banned red beacons for VIPs. Unauthorised use of any beacon or siren attracts a ₹5,000 fine.

A two-wheeler can carry only one pillion rider. Both the rider and pillion must wear ISI-certified helmets. Carrying more than one pillion is an offence under Sec. 194C.

Two-wheelers should ride in the leftmost lane on multi-lane roads. Lane-splitting (riding between lanes of stopped or slow-moving traffic) is not explicitly addressed in Indian law but is treated as dangerous riding if it endangers others.

Any modification that changes a vehicle's structure, engine, exhaust, or dimensions from the registered specification requires prior RTO approval. Unapproved modifications make the RC invalid and void your insurance.

Transport vehicles (taxis, trucks, buses) require a fitness certificate from the RTO renewed every 1–2 years. Private vehicles now require fitness testing after 15 years under the new scrappage policy.

CMVR Rule 95 requires tyres to be in good condition with adequate tread. The recommended minimum tread depth is 1.6 mm. Retreaded tyres on the front axle of commercial vehicles are prohibited. Mismatched tyre sizes on the same axle are illegal.

All four-wheelers must have at least one interior rear-view mirror and one exterior mirror on the right side. Two-wheelers must have at least one rear-view mirror (two recommended). Mirrors must provide clear rear visibility.

The Supreme Court of India (2012) banned all aftermarket window tinting/films. Factory-fitted tinted glass must allow at least 70% light transmission on the windshield and front side windows, and 50% on the rear. Any aftermarket sun film is illegal.

All vehicles must display High Security Registration Plates (HSRP) with standardised fonts, colours, and a chromium-based hologram. Fancy plates, sticker plates, plates with non-standard fonts, and obscured plates are illegal.

To drive any vehicle for hire or reward, you need a commercial driving licence (CDL). The minimum age is 18 for light transport and 20 for heavy transport (trucks, buses). A CDL requires passing additional tests including a driving test with a heavy vehicle.

Every goods vehicle must carry a valid goods permit. Cargo must be secured with ropes or chains, must not protrude beyond the body without markings, and the total weight must not exceed the registered gross vehicle weight (GVW).

Every bus must carry a valid stage carriage or contract carriage permit. Seated capacity is painted on the bus exterior. Standing passengers are permitted in city buses up to a prescribed limit. Intercity/highway buses must not allow standees.

All commercial transport vehicles must have a functioning speed governor (speed limiter). Trucks are limited to 60–80 km/h. Buses to 60–80 km/h. School buses to 40 km/h. Tampering with or removing the speed governor is a serious offence.

Every taxi and auto-rickshaw must have a valid permit, a calibrated fare meter, and a displayed rate card. Refusal to hire without valid reason is a fineable offence. The driver must take the shortest practical route.

Expressways (controlled-access highways) have additional rules: minimum speed limits (often 80–100 km/h), no pedestrians, no cyclists, no animal-drawn vehicles, no stopping on the carriageway, and mandatory toll payment.

FASTag (RFID-based electronic toll collection) is mandatory on all national highways since February 2021. Vehicles without FASTag must pay double the toll fee. Jumping or bypassing a toll plaza is a punishable offence.

Highway medians (dividers) separate opposing traffic flows. Crossing the median at any point other than a designated opening is treated as dangerous driving. Median-crossing accidents on highways have an extremely high fatality rate.
