RTT On Motorways 3 — Questions and Answers
Question 1: When joining a motorway from a slip road, which vehicles have priority on the main carriageway?
- Vehicles on the slip road
- Vehicles already on the motorway (Correct answer)
- The largest vehicle
- Whichever vehicle arrives at the merge point first
Correct answer: Vehicles already on the motorway
Traffic already on the motorway has priority; you must yield and match speed before merging safely.
Question 2: A variable message sign on a motorway shows a red X above your lane. What does this mean?
- Caution — reduce speed slightly
- Lane is closed — you must not continue in that lane (Correct answer)
- Overtaking is prohibited
- Advisory only — proceed if clear
Correct answer: Lane is closed — you must not continue in that lane
A red X is a mandatory signal indicating the lane is closed and you must move to an open lane.
Question 3: What is the minimum recommended following distance for motorcyclists on a dry motorway at 70 mph?
- 1 second
- 2 seconds
- 4 seconds (Correct answer)
- 10 seconds
Correct answer: 4 seconds
At least a 4-second gap is recommended for motorcyclists at motorway speeds to allow adequate reaction and braking time.
Question 4: You are riding on a three-lane motorway and there is no traffic in lanes 2 or 3. Which lane should you use?
- Lane 2 for better visibility
- Lane 1 (left lane) (Correct answer)
- Lane 3 to avoid lorry turbulence
- Any lane at your discretion
Correct answer: Lane 1 (left lane)
You must keep left unless overtaking; riding in lanes 2 or 3 without overtaking is an offense.
Question 5: What hazard do expansion joints or bridge gratings on a motorway pose specifically to motorcyclists?
- Reduced engine performance
- Loss of traction or wheel wobble (Correct answer)
- Overheating of tires
- Reduced fuel efficiency
Correct answer: Loss of traction or wheel wobble
Metal bridge gratings and expansion joints can cause tires to slip or wheels to track unpredictably, especially when wet.
Question 6: On a smart motorway, what does a speed limit shown in a red circle on an overhead gantry mean?
- Advisory — recommended maximum speed
- Mandatory — you must not exceed this speed (Correct answer)
- Minimum speed in that lane
- Speed limit applies only to lorries
Correct answer: Mandatory — you must not exceed this speed
A speed limit in a red circle on an overhead sign is a mandatory limit enforceable by cameras.
Question 7: A motorcyclist feels tiredness setting in after a long motorway ride. What is the best immediate action?
- Open the visor to let in cold air and continue
- Increase speed to reach the destination faster
- Pull off at the next exit or service area and rest (Correct answer)
- Drink an energy drink while riding
Correct answer: Pull off at the next exit or service area and rest
Fatigue severely impairs reaction time; stopping to rest is the only safe solution when tiredness is felt.
