What is the best practice when entering an interstate?

The best practice when entering an interstate is to look over your shoulder and match the speed of traffic. This approach ensures that you are aware of other vehicles in your blind spot and enables you to merge safely into a lane with adequate speed. Matching the speed of traffic is crucial because interstates are designed for high-speed travel, and entering at a similar speed helps maintain the flow of traffic and reduces the risk of accidents.

Entering at a slow speed can create dangerous situations, as it may disrupt the flow of traffic and cause other drivers to make sudden adjustments. Merely using turn signals is important for signaling intent, but it does not substitute the need for checking blind spots and adjusting your speed. Waiting for a police officer to assist would not only be impractical but could also lead to increased congestion and safety risks, as it does not conform to the standard procedure for merging onto highways. Proper merging techniques involve proactive measures to ensure safety and efficiency when joining high-speed roadways.
