Fuel stations on the Autobahn
Fuel stations along the Autobahn are convenient but often more expensive. Exiting the motorway to refuel in nearby towns can save money.
Watch for variable speed limits
Electronic signs display changing speed limits based on traffic, weather, or road work. These limits are legally binding and must be followed.
Prepare for road construction zones
Construction zones are common and often include reduced speed limits and narrow lanes. Stay alert and keep a safe distance from other vehicles.
Right of way when entering traffic
Vehicles already on the Autobahn have priority. Use the acceleration lane to match traffic speed before merging safely.
Construction & closures on the Autobahn
Autobahn maintenance and improvements don't escape the German penchant for obsessiveness. As a result, construction zones (Baustelle) are frequent and widespread. The standard protocol for large projects is a traffic shift, the lanes for both directions are narrowed and crammed onto one side of the Autobahn so that the other side can be worked on in its entirety. Such situations are well-marked with signs and speed limits are usually reduced greatly in these areas.
Congested Autobahn with shoulder open to traffic
In the event that a segment of Autobahn must be closed due to an accident or other emergency, pre-posted provisional detours are ready to guide traffic around the closure. As you exit, look for the U-numbered detour sign on the exit ramp - this denotes the detour route for that exit. Follow the same-numbered route over the secondary roads and you'll eventually arrive at the next downstream entrance ramp. If that entrance is also closed, just follow the next sequential detour number to reach the next entrance after that. However, there is one small gotcha, odd numbers continue in one direction, even numbers in the opposite direction. So if you're following an odd numbered route, be sure to follow the next sequential odd number (and, obviously the same goes for even-numbered routes.) These routes also come in quite handy if your patience runs-out and you want to get around a Stau.

No stopping on the Autobahn
Stopping on the Autobahn is strictly prohibited except in emergencies. If your vehicle breaks down, pull over to the shoulder and use the emergency phone if needed.
Use headlights in poor visibility
Headlights must be used during rain, fog, or low visibility conditions. Proper lighting helps other drivers see you clearly at high speeds.
Pay attention to exit numbering
Autobahn exits are numbered and clearly signposted. Move into the right lane early to avoid sudden maneuvers when approaching your exit.
Parking areas for short breaks
Smaller parking areas called Parkplatz provide quick stops for rest without full services. They are useful for stretching your legs or checking your route.
