Traffic Light Rules Flashcards

What do temporary traffic lights at a road construction site mean?

Answer: They carry the same legal force as permanent traffic lights

Temporary traffic lights at construction sites carry the same legal authority as permanent ones. You must obey them.

A traffic light shows a green arrow but no other green signal. What does this mean?

Answer: You may go only in the arrow direction — other directions are red

A green filter arrow without an accompanying green light means only traffic going in the arrow's direction may proceed. All other directions are still red.

What should you do if you are caught in the middle of a junction when the light turns red?

Answer: Proceed and clear the junction as quickly and safely as possible

If you are already in the junction when the light turns red, you should clear the junction as quickly and safely as possible. Never reverse.

At a junction with a dedicated right-turn phase, when should you turn right?

Answer: Only when the right-turn green arrow is shown

When a junction has a dedicated right-turn phase (green arrow), you should only turn right when that specific green arrow is displayed.

What is the purpose of the countdown timer displayed on some traffic lights in Singapore?

Answer: To show pedestrians how much time remains to cross

Countdown timers at pedestrian crossings show how much time pedestrians have remaining to complete their crossing safely.

Can you make a left turn on a red light in Singapore?

Answer: Yes, if there is a green left-turn arrow

You may only turn left on red if there is a green filter arrow permitting the left turn. Without the arrow, you must wait for the main green light.
