For heavy duty commercial vehicles it is recommended 4-6 seconds following distance for speeds under 30 mi/h (48 km/h), and 6-8 seconds following distance for speeds over 30 mi/h (48 km/h). [9] Rear-end collisions are the number one type of traffic collisions. [10]
The two-second rule is a rule of thumb by which a driver may maintain a safe trailing distance at any speed. [1] [2] The rule is that a driver should ideally stay at least two seconds behind any vehicle that is directly in front of his or her vehicle. It is intended for automobiles, although its general principle applies to other types of vehicles.
Using physics, math and brain science, we can come up with a pretty good estimate of proper following distance for various driving situations. Use this counting method to find safe following ...
The two-second rule tells a defensive driver the minimum distance to avoid collision in ideal driving conditions. The red car's driver picks a tree to judge a two-second safety buffer. Defensive driving describes the practice of anticipating dangerous situations, despite adverse conditions or the mistakes of others when operating a motor vehicle.
Tailgating is the action of a driver driving behind another vehicle while not leaving sufficient distance to stop without causing a collision if the vehicle in front stops suddenly. [1] The safe distance for following another vehicle varies depending on various factors including vehicle speed, weather, visibility and other road conditions. Some ...
Non-commercial vehicles have even shorter lighting distances. [116] Drivers commonly drive the maximum posted speed limit at night, often in violation of the ACDA rule [116] [110] [46] [108] and this shows up in accident data. [117] [3]
A key feature of Honda SENSING Elite is the hands-off function, which assists in steering the vehicle when the driver has their hands off the wheel, supported by adaptive in-lane driving. This aids in maintaining lane position at a pre-set speed and keeping a proper following distance from the vehicle ahead.
Adaptive cruise control (ACC) can maintain a chosen velocity and distance between a vehicle and the vehicle ahead. ACC can automatically brake or accelerate with concern to the distance between the vehicle and the vehicle ahead. [30] ACC systems with stop and go features can come to a complete stop and accelerate back to the specified speed. [31]
