BTT Traffic Light Rules 4

Question 1

At a junction with a separate cyclist signal, what should cyclists do when their signal shows red?

Accepted Answer

Stop and wait for the cyclist green signal

Answer

Cyclists must obey their dedicated signal. When it shows red, they must stop and wait for their green signal.

Question 2

What should you do if the traffic light turns amber while you are at the stop line?

Accepted Answer

Stop, as you are at the stop line and can do so safely

Answer

If you are at or behind the stop line when the amber light appears, you should stop since you can do so safely.

Question 3

A bus lane has its own traffic light showing a white 'B' signal. What does a lit white 'B' mean?

Accepted Answer

Buses may proceed

Answer

A white 'B' signal at a bus lane gives buses priority to proceed, separate from regular traffic signals.

Question 4

What is the correct action when approaching a green traffic light that has been green for a long time?

Accepted Answer

Be prepared to stop as it may change soon

Answer

A stale green light may change at any moment. Approach at a speed that allows you to stop safely if it turns amber.

Question 5

If traffic lights at a four-way junction are all flashing amber, how should you proceed?

Accepted Answer

Treat it as an uncontrolled junction — give way to traffic from the right

Answer

When all traffic lights flash amber, the junction becomes uncontrolled. Apply normal right-of-way rules and proceed with extreme caution.
