What is the maximum distance within which you must dim your high beams when following another vehicle?

When you are following another vehicle, it's essential to ensure that your high beams do not cause glare or visibility issues for the driver in front of you. In Washington State, the law requires that you dim your high beams when you are within 300 feet of the vehicle you are following. This distance is established to protect the safety of all road users, as high beams can significantly impair the vision of drivers in front, especially at night or in low-light conditions. By adhering to this requirement, you contribute to safer driving conditions and help prevent accidents that can occur due to blinding headlights.
