Can I cycle after a beer in Czechia?
No — the same zero tolerance applies on a bike as behind the wheel. A cyclist is legally the driver of a non-motorised vehicle, and riding under the influence brings a fine of CZK 7,000–25,000. The only "advantage": cyclists get no penalty points and normally keep their driving licence. Above 1 ‰, though, even cycling becomes the criminal offence of endangerment under the influence (§ 274), carrying up to 1 year — and there a court can impose a driving ban. Refusing the breath test does not pay: it is treated like a high reading. Police do check cycle paths, which are public roads. Fun fact: boaters on non-motorised vessels may go up to 0.5 ‰, while an e-bike up to 25 km/h is a bicycle.
📋 The rules
- Zero tolerance applies to cyclists
- Fine CZK 7,000–25,000 (administrative proceedings)
- No penalty points for cyclists
- Above 1 ‰: possible criminal offence, even on a bike
- Refusing a breath test is treated like a high reading
🔓 Exceptions
- Boaters on non-motorised vessels: 0.5 ‰ limit
- Pushing your bike as a pedestrian is not an offence
- Penalty points: cyclists get none — only a court can impose a driving ban, for the criminal offence above 1 ‰
⚠️ Penalties & fines
Cycling under the influence: a fine of CZK 7,000–25,000, depending on the reading and the circumstances. Above 1 ‰ it becomes the criminal offence of endangerment under the influence (§ 274 of the Criminal Code) with up to 1 year in prison — and even a cyclist can be handed a ban on driving motor vehicles there, so the licence can go after all. Refusing the breathalyser is assessed like a high reading, i.e. at the top of the band. And if you cause a crash while drunk, the liability for damage and injuries is yours.

❓ Frequently asked
What's the fine for cycling after beer?
CZK 7,000–25,000 in administrative proceedings, depending on the reading and the circumstances of the ride. Zero tolerance means even one beer can land you there — there is no "safe" threshold for cyclists.
Will I lose my driving licence?
Not for a bike misdemeanour — cyclists get no penalty points deducted. The criminal offence above 1 ‰ is different: there a court can impose a ban on driving motor vehicles, so your licence really is at risk.
Does it apply on cycle paths?
Yes — a cycle path is a public road and police can check you there exactly as on a street. Zero tolerance depends on the fact that you are driving a vehicle, not on how many cars are around you.
Can I refuse the breathalyser?
You can, but refusal is assessed like a high reading, so you land at the top of the CZK 7,000–25,000 band. It does not get you out of the sanction, it only closes the door to a milder outcome.
What about e-bikes?
A pedal-assist e-bike up to 25 km/h counts as a bicycle — the same zero tolerance and the same CZK 7,000–25,000 fines apply. The motor changes nothing legally; it mostly raises the stakes in a crash.
