At night, both drivers acknowledge each other by flashing their off-side direction indicators headlights immediately before or as they pass. It is customary for both drivers to then acknowledge each other with a wave as they pass. When opposing traffic is encountered, the first driver to reach the nearest passing place pulls over, no matter which side, and flashes the headlights to signal the other car to proceed forward. In Scotland, and places like the Isle of Man most drivers are accustomed to single-track roads. When two vehicles meet head-on, generally the drivers confer to decide in which direction lies the closest wide spot, and together they travel there, the lead vehicle necessarily in reverse gear. If lines of sight are long, and both drivers are familiar with the road, vehicles heading towards each other can adjust their speed so as to arrive at a wide spot at the same time and pass slowly, avoiding the need for either vehicle to stop.

An example of this is the M-89 reconstruction project in Plainwell, Michigan, where westbound traffic is detoured via county roads around town. A modification of this for roadways that have heavier traffic volumes is to maintain one direction on the existing roadway, and detour the other, thus not requiring the use of flaggers. The workers, who communicate through yelling, hand gestures, or radio, will periodically reverse their signs to allow time for traffic to flow in each direction. When reconstruction is being done on two-lane highways where traffic is moderately heavy, a worker will often stand at each end of the construction zone, holding a sign with "SLOW" or "GO" written on one side and "STOP" on the reverse. The reason behind this procedure is that traffic going north is in somewhat of a hurry to deliver equipment to Deadhorse, Prudhoe Bay, and the drill site over the frozen Arctic Ocean. The mountain passes on the Dalton Highway in Alaska have a rule where goods-carrying northbound truck traffic has the right of way, while returning southbound traffic has to stop, as mentioned on Ice Road Truckers. The most common example of private single-track roads are long driveways of rural properties such as country houses and farm property. Exit and entrance ramps for freeways and motorways are among common examples of one-way single-track roads. Single-track roads also exist as one-way stretches. Tunnels in remote areas can also be one lane when the tunnel is short and traffic is low, when building a hill or blasting away the mountain is too cost-prohibitive. Sometimes, for budget reasons, and where traffic is fairly low, bridges exist as single-track corridors. At least in California, it is also the vehicle going downhill that must back up, if it is too late to stop at a wide spot.Ĭhicanes are often placed on residential streets as a more aesthetic means to slow down cars. The reason seems to be that it may be harder for the vehicle going up to get started again. When practical, it is usually considered better for the vehicle going downhill to yield the right of way by stopping at a wide spot. In Peru, the second of two overland transportation routes between Cuzco and Madre de Dios Region, a 300 km heavy-truck route, is a single-track road of gravel and dirt. Forest Service and logging roads in the United States. In remote backcountry areas around the world, particularly in mountains, many roads are single-track and unmarked. One-lane road in California, United States In 2009, the A830 "Road to the Isles" and A851 on the Isle of Skye have had their single-track sections replaced with higher-quality single-carriageway road. Some A-class and B-class roads in the Highlands are still single-track, although many sections have been widened for the sake of faster travel. Sometimes two small vehicles can pass one another at a place other than a designated passing place. The same system is found very occasionally in rural England and Wales, as well as Sai Kung District in the New Territories. Signs remind drivers of slower vehicles to pull over into a passing place (or opposite it, if it is on the opposite side of the road) to let following vehicles pass, and most drivers oblige. On some roads, especially in Argyll and Bute, passing places are marked with black-and-white-striped posts. New signs tend to be square rather than diamond-shaped, as diamond signs are also used for instructions to tram drivers in cities. Passing places are generally marked with a diamond-shaped white sign with the words "passing place" on it. The term is widely used in Scotland, particularly the Highlands, to describe such roads.
