What must a driver do when entering a highway from a private road?

When entering a highway from a private road, the driver must stop and yield to the vehicles already on the highway. This traffic rule is crucial because highways typically have higher-speed traffic, and vehicles on the highway have the right of way. By stopping and yielding, the driver can assess the situation and ensure it is safe to enter the roadway, minimizing the risk of collisions. This practice is designed to enhance safety for all road users, including both highway traffic and those entering from less busy roads.

Driving at the proper speed when merging is important, but it should be done only after ensuring a safe entry point, which requires yielding. Simply entering the highway without stopping or checking for traffic could lead to dangerous situations, as you may not adequately assess the speed and distance of oncoming vehicles, increasing the potential for accidents.
