What procedure should you follow when merging into traffic on an expressway?

When merging into traffic on an expressway, following the correct procedures is vital for a safe and smooth transition. Looking over your shoulder and in your mirrors before merging is essential because it ensures you are aware of your surroundings, including the speed and position of vehicles in adjacent lanes. This awareness helps prevent collisions and allows you to make informed decisions about when and how to merge.

Speeding up before merging is also important if you have an entrance ramp, as it allows you to match the speed of the traffic on the expressway. This practice makes merging easier and safer because it reduces the chances of disrupting the flow of traffic.

Stopping completely before merging, on the other hand, should generally be avoided unless absolutely necessary, such as when it's required to yield to oncoming traffic. Stopping can create hazards for both you and the vehicles behind you, potentially leading to rear-end collisions.

By integrating these strategies—speeding up to match traffic, checking your surroundings, and avoiding unnecessary stops—you can execute a safe merge into expressway traffic. All these actions combined represent a comprehensive approach to merging that prioritizes safety and traffic flow.
