ADI Traffic Signs 2 — Questions and Answers
Question 1: What do double white lines in the centre of the road mean when the line nearest to you is solid?
- You may cross the lines to overtake if it is safe
- You must not cross or straddle the lines unless it is safe and you need to enter adjacent premises, or to pass a stationary vehicle, road works, or a pedal cycle moving at 10mph or less (Correct answer)
- The lines have no legal significance
- You may park alongside them
Correct answer: You must not cross or straddle the lines unless it is safe and you need to enter adjacent premises, or to pass a stationary vehicle, road works, or a pedal cycle moving at 10mph or less
When the line nearest to you is continuous (solid), you must not cross or straddle it except in specific circumstances: to enter or access adjacent premises, to pass a stationary vehicle, to pass road maintenance vehicles, roadworks, or a pedal cycle, horse, or road maintenance vehicle moving at 10mph or less.
Question 2: An ADI should teach that a red circular sign showing '30' indicates what?
- A recommended speed of 30mph
- A mandatory maximum speed limit of 30mph, which it is an offence to exceed (Correct answer)
- A minimum speed of 30mph
- A speed limit that only applies to learner drivers
Correct answer: A mandatory maximum speed limit of 30mph, which it is an offence to exceed
A red circular sign with a number indicates a mandatory maximum speed limit. It is an offence to exceed the displayed speed. The limit applies to all vehicles unless specific exemptions apply (e.g., emergency vehicles responding to emergencies).
Question 3: What does a circular blue sign showing '30' indicate?
- Maximum speed limit of 30mph
- Minimum speed limit of 30mph — you must not drive slower than this unless road conditions require it (Correct answer)
- Recommended speed of 30mph
- Speed limit for heavy vehicles only
Correct answer: Minimum speed limit of 30mph — you must not drive slower than this unless road conditions require it
A blue circular sign with a number indicates a minimum speed limit. Drivers must not travel slower than the displayed speed unless road or traffic conditions make it unsafe. The end of the minimum speed limit is shown by the same sign with a red diagonal line through it.
Question 4: What is indicated by a blue rectangular sign on a motorway?
- Warning of a hazard ahead
- Information and direction — motorway signs use blue backgrounds to indicate motorway-related information (Correct answer)
- A mandatory instruction to leave the motorway
- Tourist information
Correct answer: Information and direction — motorway signs use blue backgrounds to indicate motorway-related information
Motorway signs have blue backgrounds. They provide directional and informational guidance including junction numbers, destinations, distances, and motorway services. Green signs indicate primary routes, and white signs indicate non-primary routes.
Question 5: A learner asks about a sign showing a red circle with a red cross inside. What does this mean?
- Hospital ahead
- Clearway — no stopping at any time including for setting down or picking up passengers (Correct answer)
- First aid post ahead
- No right turn
Correct answer: Clearway — no stopping at any time including for setting down or picking up passengers
A clearway sign (red circle with red X) means no stopping is permitted at any time — not even briefly for setting down or picking up passengers. Vehicles must not stop on the carriageway where this sign applies.
Question 6: When teaching about road markings, what do hatched markings (diagonal lines) bordered by a solid white line indicate?
- A parking area for disabled drivers
- An area that must not be entered unless it is an emergency — they separate traffic flows or protect turning vehicles (Correct answer)
- A pedestrian crossing area
- A bus lane during operating hours
Correct answer: An area that must not be entered unless it is an emergency — they separate traffic flows or protect turning vehicles
Hatched markings bordered by a solid white line indicate an area that must not be entered except in an emergency. When bordered by a broken white line, they should not be entered unless it is safe to do so. These markings separate opposing traffic flows or protect traffic turning right.
