Stop Lines and Box Junctions

You must stop before the stop line — never on it or past it. Do not enter a box junction unless your exit 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.

What the Law Says

CMVR Rule 3 and IRC:67 require vehicles to stop at the marked stop line and not encroach on the pedestrian crossing or intersection during a red signal. Box junctions (yellow criss-cross markings) must not be entered unless the exit ahead is clear — a vehicle that enters and gets stuck is blocking cross-traffic.

💡 Why This Rule Exists

Stop lines create a safe buffer between waiting traffic and the active intersection. Encroaching past the stop line puts the vehicle into the path of crossing traffic and pedestrians. Box junction rules prevent intersection gridlock — a self-perpetuating cycle where cross-traffic blocks through-traffic, which blocks more traffic, halting the entire intersection.

Key Facts

  • 1

    Stop line: white solid transverse line across the lane.

  • 2

    Bicyclists' stop line (ASL — Advanced Stop Line): sometimes provided ahead of the vehicle stop line; cyclists may use this area.

  • 3

    Box junction: yellow criss-cross hatching. Enter only if exit is clear.

  • 4

    Parking on yellow kerb lines = no parking; red kerb = no stopping.

  • 5

    If the stop line is worn/faded, stop before the pedestrian crossing, or if absent, before the intersection.

⚠️ Common Violations

  • Vehicles stopping on or past the stop line, blocking the pedestrian phase.

  • Entering a box junction in heavy traffic and blocking cross-traffic.
