When race officials are ready to open pit lane, a green light will come on in the rear window of the safety car. One lap before a green flag, the pace car will shut off its lights to signal drivers to line up double file. Unlike most series in motorsport, owing to NASCAR's short-track roots, each track usually offers its own safety car, typically from the manufacturer, but in recent years, it has been a local dealer or association of regional dealerships-provided Safety car. Tracks that use Toyota safety cars will use a Toyota Camry Hybrid, while Ford tracks will use a Ford Mustang, while Chevrolet tracks use a Chevrolet Camaro and most Dodge tracks use a Dodge Challenger. If a manufacturer is promoting a new vehicle, they will often use the new car instead of the standard-specification safety car. For the Truck Series, which races pickup trucks instead of cars, the safety "car" is often a pickup. Tracks affiliated with a local or regional Chevrolet dealership will use a Chevrolet Silverado, while Chrysler dealership-affiliated tracks will use a Ram 1500. Ford-affiliated tracks will often use the F-Series, but Toyota-affiliated tracks are less likely to use the Toyota Tundra, but prefer marketing the Camry Hybrid. However, Ford and Toyota manufacturer sponsored tracks will prefer the Mustang and Camry, respectively, instead of a truck, and occasionally, pickup trucks have been used as pace vehicles for Cup Series and Xfinity races. Since NASCAR does not allow speedometers or electronic speed limiting devices, the pace car circles the track at pit road speed during the warm-up laps. This allows each driver to note the RPM at which pit road speed is maintained. Drivers exceeding that speed on pit road will be penalized, typically a "drive-through" or "stop and go" penalty, costing them valuable track position. Since mid-2004, NASCAR official Brett Bodine has driven the vehicle during official race functions during Cup Series races. Other famous NASCAR pace car drivers include Robert "Buster" Auton and Elmo Langley. At many races, NASCAR has an honorary pace car driver that actually drives a car during the parade laps. Depending on the driver's skill, some drivers are allowed to pace the field right up to the dropping of the green flag. Some famous drivers have been Jay Leno, Richard Hammond, Luke Wilson, Rob Gronkowski, Guy Fieri and many others. The beneficiary rule (informally known as the "lucky
