    Brake firmly while still in the main carriageway lane to ensure you reach the slip road at low speed
  2. Maintain normal cruising speed until you have fully entered the deceleration lane before applying the brakesAnswer
  3. C
    Depress the clutch pedal and coast across the painted chevron markings straight into the slip road
  4. D
    Move swiftly across multiple lanes directly onto the exit without checking your left-side blind spot

Answer

Maintain normal cruising speed until you have fully entered the deceleration lane before applying the brakes
According to Highway Code Rules 272 and 273, you should maintain your speed on the main carriageway and only reduce speed once you are safely in the deceleration lane, ensuring following vehicles are not impeded.

Step-by-Step Solution

1
Position the vehicle early in the left-hand lane using the Mirror-Signal-Manoeuvre routine.
The vehicle is safely positioned to enter the exit lane without sudden steering.
Highway Code Rule 272 requires drivers to move to the left lane well before their exit.
2
Signal left at the countdown markers and maintain carriageway speed until crossing onto the deceleration slip road.
The flow of traffic in the live running lane is not disrupted.
Slowing down on the main carriageway creates a hazard for following vehicles travelling at high speed.
3
Brake progressively within the slip road while monitoring the speedometer.
Speed is reduced safely to match the slip road layout or junction requirements.
Highway Code Rule 273 highlights that drivers often suffer from velocitation and underestimate their speed after prolonged motorway driving.
