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 ...
Safety in NASCAR has evolved into one of the biggest concerns in stock car racing's largest sanctioning body. Mainly after the death of Dale Earnhardt , a seven-time Winston Cup Series champion, NASCAR has decided to change all of their safety policies, such as the use of the HANS device .
Environmental conditions can cause degradation of glass beads, leading to release of incorporated heavy metals into the environment. [3] While abrasion may dislodge these beads from the road marking itself, the reaction of these beads with an aqueous environment vastly accelerate their decomposition and heavy metal release.
[1] [17] Gordon spun and made two pit stops to repair car damage. All drivers chose to make pit stops under caution. [17] Stewart maintained the lead at the lap-178 but he lost it to Earnhardt on the following lap. [18] Stewart attempted to retake the first position by drawing alongside Earnhardt on lap 187 but was unsuccessful. [17]
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.
Abrasion may dislodge these beads from the road marking itself, and the reaction of these beads with an aqueous environment vastly accelerates their decomposition and heavy metal release. [citation needed] During both routine road marking removal and harsh environmental conditions, these glass beads can degrade and leach incorporated heavy metals.
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 ...
