This flag is shown if the driver or pit crew violates a rule (e.g., speeding through the pits), if the vehicle has sufficient mechanical damage that it is a hazard to other drivers, if the vehicle cannot maintain the minimum required speed (varies by track; typically disclosed in the pre-race drivers' meeting), or if a driver has been driving ...
The impact energy to the car and driver are reduced, and the car is likewise not propelled back into traffic on the racing surface. The SAFER barrier also lessens damage to the car itself, thereby reducing repair costs. After its introduction in 2002, nearly every oval track on the IndyCar and NASCAR circuits had the device installed by 2005 ...
The orange markers separate opposing traffic lanes. The blue marker denotes a fire hydrant on the left sidewalk. A raised pavement marker is a safety device used on roads. These devices are usually made with plastic, ceramic, thermoplastic paint, glass or occasionally metal, and come in a variety of shapes and colors.
Traffic barrier with a pedestrian guardrail behind it. Traffic barriers (known in North America as guardrails or guard rails, [1] in Britain as crash barriers, [2] and in auto racing as Armco barriers [3]) keep vehicles within their roadway and prevent them from colliding with dangerous obstacles such as boulders, sign supports, trees, bridge abutments, buildings, walls, and large storm drains ...
By April 1991, NASCAR implemented the current policy of pit road speed limits. The speed limit depends on the size of the track and the size of pit road. NASCAR uses an electronic scoring system, similar to the VASCAR system, to monitor the speeds of cars on pit road by measuring the time it takes to get from checkpoint to checkpoint. The cars ...
These are often used in conjunction with two rows of the temporary cat's eyes to divide traffic moving in opposite directions during motorway roadworks. Solar-powered cat's eyes known as solar road studs and showing a red or amber LED to traffic, have been introduced on roads regarded as particularly dangerous at locations throughout the world.
PJ1 TrackBite (formerly known as VHT TrackBite or simply VHT) is a custom formulated synthetic resin, typically black in color, used in drag racing to either increase the traction of a car's tires or as a sealer for newly ground and/or resurfaced race tracks. [1] It stays sticky for weeks, has fire-retardant properties, and is hydrophobic. It ...
Chicanes can make slipstreaming less potent and break up pelotons during motor races. [3] The term is used in other types of racing, such as bobsleigh, to indicate a similar shift in the course or track. A slower driver or vehicle that delays competitors is sometimes disparaged as a mobile chicane or moving chicane.
