What should you do to enter a gap in highway traffic?

To safely enter a gap in highway traffic, it is essential to conduct a thorough assessment of your surroundings. Checking behind you ensures that there is adequate space for you to merge without interfering with the vehicles already in motion. Additionally, watching the vehicle ahead helps you maintain a safe distance and understand its speed and behavior, allowing for a smoother transition into the traffic flow. This proactive approach minimizes the risk of collisions and enhances overall safety on the road.

The other choices suggest actions that could lead to dangerous situations. Accelerating without checking does not account for vehicles that may be approaching from behind, while creeping into a gap without looking ignores the need for an awareness of both the vehicles rear and ahead. Waiting for a traffic light to change is irrelevant to merging onto a highway, as it does not apply to gaps in moving traffic.
