For high-intensity beams, no part may strike the roadway beyond what distance from the vehicle?

The distance beyond which high-intensity beams should not strike the roadway is specifically set to ensure safety and visibility without causing undue glare or distraction to other drivers. The correct answer is 75 feet, which provides a balance between effective illumination of the area immediately surrounding the vehicle and the need to minimize the risk of blinding other road users.

When high-intensity beams are used, they can create significant glare if they extend too far down the road. The limitation to 75 feet helps maintain a safer driving environment by ensuring that while the driver can see well ahead, they do not illuminate the roadway excessively, which could impact oncoming traffic. This regulation reflects a careful consideration for both visibility and the safety of all road users.
