Abstract: An installation for affording a motor vehicle driver practice to improve his reactions and behavior in an emergency situation. A shaft with a movably disposed symbol-bearing member therein is arranged in a test-roadway. Operating devices are provided for moving the symbol-bearing member partway out of the shaft and for completely returning the symbol-bearing member to within the shaft. An electric signal is produced by a device disposed in front of the shaft to control the operating devices when a motor vehicle approaches the shaft. The symbol-bearing member is suddenly caused to move out of the shaft when a motor vehicle approaches the shaft and returned before the vehicle reaches the symbol-bearing member.
