Zorluk: OrtaJoining the Motorway

You are approaching a busy motorway via an entry slip road in clear daylight conditions. In what chronological sequence should you carry out these driving actions to join the carriageway safely?

  1. 1Scan the main carriageway ahead and to your right to assess traffic speed and identify potential gaps.
  2. 2Signal right in good time to communicate your intention to vehicles already on the motorway.
  3. 3Use the acceleration lane to match your vehicle's speed to the traffic flowing in the left-hand lane.
  4. 4Perform a final right-hand blind-spot shoulder check and steer smoothly into the selected gap.

Cevap

The correct sequence is: scan the main carriageway to assess traffic flow and identify gaps, signal right in good time, match your speed to lane 1 traffic within the acceleration lane, and complete a final blind-spot shoulder check before merging smoothly into the gap.
Under Rule 259 of the Highway Code, drivers joining a motorway must give priority to traffic already on the carriageway. The safe routine begins with early scanning of traffic from the slip road, signalling right in good time, utilizing the full length of the acceleration lane to match the speed of lane 1 traffic, and verifying the blind spot over the right shoulder before steering smoothly into an appropriate gap.

Adım Adım Çözüm

1
Observe traffic on the motorway carriageway from the slip road.
You identify traffic speed, volume, and suitable gaps in the flow.
Early situational awareness gives you time to plan your acceleration profile and merge strategy.
2
Activate the right turn signal.
Your intention to join the motorway is clearly communicated to other road users.
Early signalling allows drivers in the left-hand lane to anticipate your entry and adjust their lane or speed if necessary.
3
Accelerate along the acceleration lane to match the cruising speed of lane 1.
Your vehicle reaches a compatible merging speed with main carriageway traffic.
Joining at a speed substantially slower or faster than the existing traffic creates severe collision hazards.
4
Check mirrors and the right blind spot, then steer smoothly into the gap.
You merge seamlessly without cutting off other vehicles.
Mirrors alone do not reveal vehicles sitting adjacent to your rear quarter; a quick shoulder check verifies the merge zone is completely clear.
