ADI Traffic Signs

Question 1

What does a circular sign with a red border and no other markings inside (other than the white background) indicate?

Accepted Answer

No vehicles allowed (except pedal cycles being pushed)

Answer

A circular white sign with a red border and no other markings is the 'no vehicles' sign, prohibiting all motor vehicles. Pedal cycles may be pushed but not ridden. This sign is used to close roads to motor traffic.

Question 2

A triangular sign with a red border is classified as what type of road sign?

Accepted Answer

Warning sign — alerting drivers to a hazard ahead

Answer

Triangular signs with red borders are warning signs. They alert drivers to hazards ahead such as bends, junctions, crossings, or road conditions. The shape and colour are standardised across the UK highway sign system.

Question 3

What does a circular blue sign with a white upward-pointing arrow indicate?

Accepted Answer

Ahead only — vehicles must proceed in the direction shown

Answer

A circular blue sign with a white upward arrow means 'ahead only' — drivers must continue straight ahead and cannot turn. Blue circular signs give positive (mandatory) instructions, unlike red circular signs which give prohibitions.

Question 4

An ADI is teaching a learner about speed limit signs. What does a white circular sign with a black diagonal stripe indicate?

Accepted Answer

The national speed limit applies

Answer

A white circular sign with a black diagonal stripe indicates that the national speed limit applies. This is 60mph on single carriageways and 70mph on dual carriageways and motorways. It does not mean 'no limit' — the national speed limit still applies.

Question 5

What does a brown rectangular sign with white text indicate?

Accepted Answer

Tourist information — directing to tourist attractions, heritage sites, or places of interest

Answer

Brown signs are tourist information signs directing drivers to tourist attractions, heritage sites, leisure facilities, and other places of interest. They are distinct from green (primary route) and white (non-primary route) direction signs.
