What should a driver do when joining a motorway from a slip road?

When joining a motorway from a slip road, the driver should aim to match the vehicle speed to the traffic already on the motorway and merge into a suitable gap. This approach is crucial for maintaining a smooth flow of traffic and ensuring safety.

By accelerating to match the speed of vehicles on the motorway, a driver can more easily find an appropriate gap to enter without causing disruptions. If a driver goes too slowly, they might create a hazardous situation for both themselves and other motorists. Similarly, completely stopping before merging can lead to potential collisions, as vehicles behind would not expect this behavior.

Making sure to find a suitable gap helps in preventing accidents caused by abrupt merging or sudden lane changes, enhancing overall road safety. Merging only when the slip road is clear would not be safe or practical in most situations, as slip roads are often busy, and waiting could result in increased traffic congestion and risk of rear-end collisions. Thus, adjusting speed appropriately and merging smoothly is the best practice when joining a motorway.
