A car passes a slower moving truck, using a passing lane on the A2 motorway in Slovenia. A passing lane (North American English), overtaking lane (English outside North America) is a lane on a multi-lane highway or motorway closest to the median of the road (the central reservation) used for passing vehicles in other lanes.
For example, New Mexico does not address lane splitting by name, but has language requiring turn signals be used continuously for at least 100 ft (30 m) before changing lanes. [67] as well as other codes which may be cited by an officer. [68] [69] Many other states have derived identical codes from the Uniform Vehicle Code. [70]
Existing bridges can remain part of the Interstate system if they have at least 12-foot-wide (3.7 m) lanes with 3.5-foot (1.1 m) shoulder on the left and a 10-foot (3.0 m) shoulder on the right, except that longer bridges can have 3.5 feet (1.1 m) shoulders on both sides. For all bridges, the railing should be upgraded if necessary.
In terms of optimal spacing between the path and motorist lanes, it is generally practice to use 2–5 meters at signalised crossings and one car length >5 m at unsignalised intersections. Providing more buffer space allows vehicles, particularly those turning out of smaller roads, to queue in the waiting area.
The Uniform Vehicle Code (UVC) is a model act by the National Committee on Uniform Traffic Laws and Ordinances, a private non-profit organization. Most of the members are state governments, in addition to some related organizations. The extent to which the code is used varies by each state, territory, and Native American tribe. It was last ...
The late merge method has not been found to increase throughput (throughput is the number of vehicles that pass through a point in a given period of time). However, it considerably reduces both queue/line ("backup") length (because drivers use the ending lane until it ends) and speed differences between the two lanes, increasing safety. [3]
A modern Autobahn divided highway with two lanes per direction has lanes 3.75 m (12.3 ft) wide with an additional clearance of 0.50 m (20 in) on each side; with three lanes per direction this becomes 3.75 m (12.3 ft) for the rightmost lane and 3.5 m (11 ft) for the other lanes. Urban access roads and roads in low-density areas may have lanes as ...
