Can I turn right on red on a bike in Czechia?
No — in Czechia you may not turn on red, even by bike. The cyclists-right-on-red rule used in Vienna, Paris and German cities does not exist in Czech law: a red signal means stop for every driver, cyclists included. The only legal path is the supplementary green arrow — when it shines together with red you may turn right, but must yield to vehicles in the flowing direction and to pedestrians on the crossing. The detail most people miss: where a small cyclist signal is installed it overrides the main light, and on a cycle crossing you have priority only on green. There is exactly one legal workaround: dismount and push the bike across as a pedestrian — riding over the crossing is an offence.
📋 The rules
- Red = stop for cyclists too; no Czech exception exists
- Supplementary green arrow: right turn allowed, yielding to everyone
- On cycle crossings you have priority only on green
- Small cyclist signals override the main lights where installed
- Dismounting and walking the crossing as a pedestrian is the legal workaround
🔓 Exceptions
- The supplementary green arrow shining with red (yield obligation)
- A police officer directing traffic overrides the signals
- A small cyclist signal, where installed: it takes precedence over the main light
⚠️ Penalties & fines
Running a red on a bike: an on-the-spot fine, with no penalty points and normally no risk to your driving licence. A car driver pays CZK 4,000–10,000 in proceedings for the same thing and collects 6 points; cyclist bands are lower, yet endangering pedestrians pushes the case into proceedings and the amount climbs. The most expensive item is not the fine but the liability: cause a crash after running a red and the full blame for damage and injuries is yours. And bypassing the light across the crossing without dismounting is a separate offence.

❓ Frequently asked
Austria and Germany allow it. Czechia doesn't?
Correct — Vienna and German cities use special cyclist signs and signals, and Czech law has no such provision. Until that signage exists here, red applies to a bike exactly as it does to a car, wherever you learned to ride.
What does the green arrow mean?
When the supplementary green arrow shines together with red, you may turn right, by car or by bike. It gives you no priority though: you must let through all flowing traffic and pedestrians on the crossing first.
Does the small bike signal or the main light apply to me?
If the junction has a small cyclist signal, you follow it — it takes precedence over the main light. Where there is none, the ordinary vehicle signal applies, because a bicycle counts as a vehicle in law.
Can I bypass the red via the crossing?
Only by dismounting and pushing the bike as a pedestrian — then you are a pedestrian and the crossing is yours. Riding across it is an offence, and on a cycle crossing you have priority only on green.
What does running a red cost a cyclist?
An on-the-spot fine with no points; the bands are lower than for car drivers, who pay CZK 4,000–10,000 and lose 6 points. If you endangered pedestrians, the case goes into proceedings and the amount rises sharply.
