ADI Road Procedure & Highway Code 1 — Questions and Answers
Question 1: When emerging from a side road onto a main road with limited visibility, what should a driver do?
- Accelerate quickly to merge with traffic
- Edge forward slowly until a clear view is obtained, then proceed when safe (Correct answer)
- Sound the horn before emerging
- Wait for a gap of at least 4 seconds before moving
Correct answer: Edge forward slowly until a clear view is obtained, then proceed when safe
Edging forward slowly at junctions with limited visibility allows the driver to extend their sightline gradually without committing to the manoeuvre until it is safe.
Question 2: What is the correct lane discipline on a three-lane motorway in normal driving conditions?
- Drive in the middle lane at all times for safety
- Keep to the left lane unless overtaking (Correct answer)
- Use all lanes equally to prevent tailgating
- Use the right lane at speeds above 60 mph
Correct answer: Keep to the left lane unless overtaking
Rule 264 of the Highway Code requires drivers to keep left unless overtaking; middle- or right-lane hogging is a traffic offence under the Highway Code rules.
Question 3: At a junction controlled by traffic lights that have failed, drivers should:
- Treat the junction as an uncontrolled junction and give way to the right
- Treat it as a 'give way' junction and proceed with caution (Correct answer)
- Stop and call the police before proceeding
- Give way to all traffic from all directions
Correct answer: Treat it as a 'give way' junction and proceed with caution
When traffic lights have failed, the junction becomes effectively uncontrolled; drivers must treat it as a 'give way' and proceed with care, observing the usual right-of-way conventions.
Question 4: The 'two-second rule' for following distance should be extended to how many seconds in wet conditions?
- 2 seconds
- 3 seconds
- 4 seconds (Correct answer)
- 6 seconds
Correct answer: 4 seconds
In wet conditions braking distances at least double; the Highway Code recommends at least doubling the following distance, extending the gap to a minimum of four seconds.
Question 5: When following a large vehicle such as an HGV, why should you leave a greater gap than normal?
- To allow other drivers to overtake both vehicles
- Because your forward view is restricted and braking distances for the HGV are greater (Correct answer)
- Because HGVs are allowed to travel at higher speeds
- To comply with a legal minimum following distance rule
Correct answer: Because your forward view is restricted and braking distances for the HGV are greater
Large vehicles obstruct the following driver's view ahead, and their extended stopping distances mean any impact from behind would be more severe, requiring a larger safety gap.
Question 6: Before reversing, a driver should always:
- Sound the horn three times
- Check all around the vehicle including blind spots for pedestrians and cyclists (Correct answer)
- Switch on hazard warning lights
- Ask a passenger to direct from outside
Correct answer: Check all around the vehicle including blind spots for pedestrians and cyclists
Before reversing, the driver must check all mirrors and blind spots, especially for pedestrians, cyclists and children who may be in close proximity and out of the driver's line of sight.
