(2) U-turns are never permitted on— (a) Autobahns. (b) Multilane highways. (c) Roads outside city limits except where the center line is broken and traffic is clear so that the turn can be made without endangering other vehicles. e. Fatigue.Driving while fatigued is the cause of many single-car accidents. Individuals taking medication should ensure the medication will not affect their driving ability. During long trips, the driver should stop and rest, walk around, or drink coffee or fluids at least every 2 hours. Drivers also should make sure there is enough fresh air circulating inside the car. f. German Police Hand Signals.The signals used by German police officers are different from those used by police officers in the United States. These signals and their meanings are shown in figures 1 through 5. The basic rule is that traffic parallel to the outstretched arms of the officer may proceed and traffic facing the front or back of the officer must wait. German police officer signals take priority over traffic signals, even if the traffic signals are operating. When approaching an intersection, drivers must be alert for a red traffic signal or a police officer standing in this position, which means the driver must come to a complete stop. Note that this officer’s signal to stop applies to drivers in front of and behind him, not to drivers to his right and left.
