The rule is the specific spatial case of the common law basic speed rule, [13] and an application of volenti non fit injuria. The two-second rule may be the limiting factor governing the ACDA, when the speed of forward traffic is what limits the basic safe speed, and a primary hazard of collision could result from following any closer. [2] [3]
The two-second rule provides a simpler way of perceiving the distance. To estimate the time, a driver can wait until the rear end of the vehicle in front passes any distinct and fixed point on the roadway—e.g. a road sign, mailbox, line/crack/patch in the road. After the car ahead passes a given fixed point, the front of one's car should pass ...
Traffic lights control flows of traffic using social norms and legal rules. In most jurisdictions, it is against the law to disobey traffic signals and the police, or devices such as red light cameras, can issue fines or other penalties – and in some cases prosecute – drivers who break those laws.

More commonly, curve N 1 is known as the arrival curve of vehicles at location X 1 and curve N 2 is known as the arrival curve of vehicles at location X 2. Using a one-lane signalized approach to an intersection as an example, where X 1 is the location of the stop bar at the approach and X 2 is an arbitrary line on the receiving lane just ...
Traffic signal preemption (also called traffic signal prioritisation) is a system that allows an operator to override the normal operation of traffic lights.The most common use of these systems manipulates traffic signals in the path of an emergency vehicle, halting conflicting traffic and allowing the emergency vehicle right-of-way, thereby reducing response times and enhancing traffic safety.
Traffic. Crossing from Fort Lee, Bergen County, New Jersey, into Manhattan in heavy automobile traffic on the George Washington Bridge, the world's busiest motor vehicle bridge, transporting approximately 300,000 cars and trucks daily across the Hudson River. Traffic comprises pedestrians, vehicles, ridden or herded animals, trains, and other ...
The maximum speed limit on rural two-lane roads ranges from 50 mph (80 km/h) in parts of the northeast to 75 mph (120 km/h) in parts of Texas. On rural Interstate Highways and other freeways, the speed limit ranges from 60 mph (96 km/h) in Hawaii to 85 mph (136 km/h) in parts of Texas. All roads in the United States have a speed limit, but it ...
An uncontrolled intersection in suburban Melbourne, Australia. At uncontrolled 4-way intersections, the common rules are: . give way to traffic approaching from the passenger's side (i.e. from the right in countries that drive on the right-hand side, a rule known as priority to the right, and vice versa) [citation needed]
