What action should you take when entering a highway?

When entering a highway, accelerating to match the speed of traffic and merging safely is essential for ensuring a smooth transition into the flow of vehicles. Highways typically have higher speed limits, and matching the speed of oncoming traffic helps maintain safety by preventing abrupt slowdowns that could lead to accidents.

This action allows you to merge without significantly disrupting the speed of vehicles already on the highway, which is vital for avoiding collisions and ensuring the safety of all drivers. Properly gauging the speed of traffic will help you find a suitable gap to merge into, thereby reducing the risk of creating hazardous situations.

In contrast, decelerating to let traffic pass can create confusion and increase the likelihood of accidents, as other drivers may not anticipate a vehicle slowing down while entering the highway. Using the emergency lane is dangerous and illegal; it's meant for breakdowns or emergencies only. Waiting for a police escort is unnecessary and impractical, as highways are designed for individual drivers to merge responsibly and safely without needing escorts.
