with ice during winter. Conventional rallying also takes place on ice. Most notably, the tarmac of the Monte Carlo Rally is occasionally covered with snow and ice. The Sno*Drift rally in Michigan is another example of such events. Race vehicle There are many classes of racing vehicles. The racing vehicles are frequently divided into studded or non-studded tire classes. Nearly all dirt track racing vehicles could be raced on ice. Flying snow and ice powder limits visibility, so some vehicles are required to have a bright light, normally red or yellow, on the back of the car for greater visibility in the powder. Non-studded cars are selected by their weight since non-studded cars cannot carry high speed through a corner and cars cannot get much power to the slippery surface. Lightweight front-wheel drive cars are generally the quickest. Ice racing in film Ice racing was featured in the 1969 James Bond film On Her Majesty's Secret Service with George Lazenby and Diana Rigg as they attempted to evade their pursuers. The track was in Switzerland. Motorcycle ice racing footage can be seen in the Bruce Brown documentary On Any Sunday.
