# Temporary traffic lights ahead — UK road sign

Warns drivers that portable or temporary traffic signals control road movement ahead.

The 'temporary traffic lights ahead' sign alerts drivers to portable traffic control signals, typically used during roadworks or single-lane closures.

It gives advance warning so drivers can slow down before reaching potentially stopped queues or blind work zones.

## What this sign means

The sign displays a traffic light graphic showing red, amber, and green circles within a red warning triangle.

It indicates temporary 2-way or multi-way signals regulating traffic flow around an obstruction or narrow section.

- Red, amber, and green light graphic in a red triangle
- Warns of portable traffic signal controls
- Often accompanied by 'Wait here on red' signs

## What to do when you see it

Slow down early, look out for queued vehicles, and prepare to stop cleanly at the 'Wait Here' sign if the signal turns red.

- Reduce speed and be prepared to stop
- Stop at the marked line or 'Wait Here' board on red
- Do not proceed on amber unless unsafe to stop

## How this sign is tested

Theory questions focus on UK traffic light sequences and rules governing temporary control setups.

- Recognising standard UK traffic light sequences
- Driver duties at temporary light stop lines
- Hazard perception involving queues near temporary signals

## Common mistakes

Jumping a red light because the road ahead appears clear, ignoring the fact that oncoming traffic may have a green phase.

Your theory certificate lasts two years. Most learners who use it quickly do it with an intensive course — a block of hours with a DVSA approved instructor and a practical test at the end, instead of one lesson a week for months.
