Speed and Safety

German Cars & the Autobahn

Course 1 · Chapter 9 · Speed, Safety and the Speed-Limit Debate

The stretches of Autobahn without a posted speed limit are the best-known fact about German roads, and the question whether to impose a general limit has been argued for decades. This chapter sets out what the rules actually are, how the limits developed, what the arguments are on each side, and what a visitor needs to know. It aims to describe the debate fairly and not to settle it. Figures change from year to year and between sources, so all are flagged "check" and should be looked up on current official sites.

What the Rules Say

No general limit

There is no nationwide maximum speed on the motorway network. Roughly 70 per cent of the length is reported to have no posted limit, with the rest limited at 100, 120 or 130 km/h or by variable signs (check; counts differ with date and method).

A recommended speed

On unposted stretches a recommended speed of 130 km/h applies (Richtgeschwindigkeit). Exceeding it is not an offence in itself, but a driver involved in an accident at higher speed may share liability (check the details).

Other rules

Drivers must keep to the right except to overtake, must not overtake on the right in ordinary traffic, and since 2017 must form an emergency corridor in a jam (check). A vehicle must be able to exceed 60 km/h to use the Autobahn (check).

A Short History of Limits

Period (check each)	Rule
1930s	The Nazi-era motorways had no general limit, and little traffic (Chapter 5), though limits in towns were introduced in 1934.
1950s	A general limit outside towns was lifted in the early 1950s, and a 50 km/h limit in built-up areas followed in 1957.
1973	The oil crisis led to car-free Sundays and a temporary motorway limit of 100 km/h, lifted in 1974.
1972 to 1978	A 100 km/h limit on rural roads was introduced in 1972 (Chapter 7), and the 130 km/h recommendation for motorways in 1978.
East Germany	The GDR had a general limit on its motorways (usually given as 100 km/h), which ended with unification (check).

The Debate

For a general limit. Road-safety researchers, environmental groups and some politicians argue that a limit would cut deaths and injuries and reduce carbon dioxide and noise, with a low cost to most drivers (check each claim against the studies).
Against. The motoring club ADAC has historically opposed a general limit, and some politicians and many drivers argue that the Autobahn is already among the safest road types and that a limit would restrict freedom for little benefit (check; positions change over time).
Polls. Surveys have often found a majority in favour of a general limit, though the size varies with the question and the date (check).
Politics. The Greens and Social Democrats have tended to favour a limit, and the Free Democrats and parts of the Christian Democrats have opposed it. Proposals were rejected or sidelined repeatedly, including in the coalition negotiations of 2021 (check).
Symbol. Many Germans treat unrestricted stretches as a symbol of freedom and of engineering pride, and the debate is not only about safety (check how widely held this view is).

What the statistics show Per kilometre driven, the Autobahn is statistically safer than country roads, since it has no oncoming traffic, no crossings and separated carriageways. This is often cited by opponents of a limit. Supporters answer that deaths at high speed are worse, that a limit would reduce them further, and that the fairer comparison is between Autobahn stretches with and without limits (check the studies, which give different estimates). Both sides use true figures to support different conclusions, so ask which comparison each is making.

Advice for Visitors

The left lane is for overtaking. Faster vehicles can approach from far behind, so check mirrors carefully and return to the right after overtaking (check).
Posted limits are enforced. Cameras and fines apply, and limits at roadworks and in built-up areas are strict (check).
Emergency corridor. In a jam, vehicles move apart to leave a lane for emergency vehicles, and failing to do so is an offence (check).
Hire cars. A rental car is subject to the same rules, and the recommended speed is a sensible guide.
Illegal races. Organising or taking part in illegal car races is a criminal offence in Germany since 2017 (check).

A British comparison British motorways have a national limit of 70 mph (about 113 km/h), set experimentally in 1965 and made permanent in 1967 (check). British drivers visiting Germany often expect the unrestricted stretches to be common but find many limited sections and heavy traffic. Britain's motorway safety record is among the best in Europe, which makes it a standard comparison in the German debate (check).

Check the details Speed rules, percentages and statistics change, and sources differ. This chapter is a description of a debate, not legal or driving advice. Check the current rules on the official German transport sites before driving, and treat claims from interested parties (clubs, campaigns, manufacturers) as arguments to weigh.

Exercises

Exercise 1

Explain what "no speed limit on the Autobahn" does and does not mean, using the recommended speed and the share of the network.

→ Solution

Exercise 2

Set out the main arguments on each side of the general-limit debate, and say which statistics each side relies on.

→ Solution

Exercise 3

Explain how both sides can quote accurate figures and still disagree, and how you would find a fairer comparison.

→ Solution

Quick Reference

Rule: no general limit; recommended 130 km/h (check)
Share: roughly 70 per cent unposted (check)
History: limits in towns, rural roads from 1972, oil crisis 1973 (check)
Debate: safety and climate against freedom and per-kilometre safety
The caution: accurate figures can support opposite conclusions
