Explanation
When entering highway traffic, merge only when there is enough space for your vehicle. Ideally, look for a gap of at least 4 seconds - this allows for a 2-second following distance in front of and behind your vehicle. Do not attempt to merge into a small opening, as it can close quickly and leave you with no room to react. Choose a gap that gives you a safe cushion of space so you can merge smoothly and avoid cutting off other drivers.
