Left Turns at Traffic Lights: Safe Gaps, Yellow Lights & Red-Light Runners

Study actual slowing behaviour and clear a legally entered intersection only when safe.

Video breakdown

Study the lesson by section

Each section below follows an explanation or demonstration in the video. Select a section to play from that point, then practise the skill with appropriate supervision.

0:02

Plan the gap early but make the final decision from the current view

The student declines an initial opportunity. The replay separates an early estimate from the final decision near the turning position. Keep the option to stop while observing oncoming traffic and pedestrians; do not commit just because the approach initially looked clear.

2:58

Prepare for a usable gap without following blindly

A second gap appears after the first car passes, but the student is not yet ready to use it. Practise timing and observation with an instructor so you can recognize an opportunity while still leaving a generous safety buffer.

3:35

Watch which vehicles actually slow when yellow appears

Most approaching vehicles slow, but one continues through late yellow and red. Read actual speed changes instead of assuming every driver will stop. The turn must wait for a safe path even when another driver is violating the signal.

5:30

Account for hills and speeding without assuming signal timing

The instructor discusses the downhill approach at this Victoria junction. Slope and excess speed can affect a driver’s behaviour, but do not assume a universal three-second yellow interval. Continue judging the real approach and stopping movement.

6:27

Distinguish stopping before entry from safely clearing after entry

If you legally entered on green and are waiting to turn, clear the junction when the conflict is safe. Yellow does not require reversing to the line or cutting across an oncoming vehicle to escape before red. Stay controlled and yield until the path clears.

8:42

Observe braking behaviour before any forward movement

The replay contrasts a non-stopping vehicle with vehicles slowing normally. Keep any cautious forward adjustment within a safe, clear path and remain able to stop. The suggestion to observe from a safe stationary place can help build recognition without driving.

10:29

Use the timing comparison to understand the need for a buffer

The instructor compares the actual turn time with the earlier vehicle’s approach. These numbers illustrate why a last-second gap is poor judgement, not a universal formula. Speed, visibility, turning distance and vehicle performance all affect the room needed.

12:08

Keep the wheels straight until the turn is safe

The final point explains why angling left while waiting is dangerous when traffic continues toward you. Keep the vehicle aligned so any controlled forward movement stays out of the opposing path, then steer into the turn only when it is safe.
