Summary of 4 Popular Motorcycle Offenses with Maximum Fines up to 4,000 Baht

For all motorcyclists or "two-wheelers," riding safely and in accordance with the law is the foremost priority. This not only reduces the risk of accidents but also helps protect your wallet from fines.

Here are four common offenses that motorbike riders often get fined for, along with the latest "penalty fines" rates.

1. Not wearing a helmet (for both rider and passenger)

This is the most important safety gear, yet it is also the most frequently violated rule. The law specifies penalties as follows:

Rider not wearing a helmet: fine up to 2,000 baht.

Passenger not wearing a helmet: fine up to 4,000 baht, imposed on the rider.

A caution: if you are the rider and your passenger refuses to wear a helmet, you are responsible for paying the fine. So always remind your passenger to wear a helmet before riding.

2. Exhaust pipe producing noise above the standard limit

For those who like to customize their bikes for a louder sound, causing disturbance to others on the road and the community, the penalty is severe.

Penalty: fine up to 4,000 baht.

3. Failure to display the tax disc (circular sticker)

Many people think paying the annual tax and storing the disc under the seat or in a bag is enough, but the law clearly requires it to be "displayed" visibly.

Penalty: fine up to 2,000 baht.

Recommendation: attach the tax disc inside a waterproof capsule and fix it on the vehicle where officials can easily see it.

4. No side mirrors

Side mirrors are essential for visibility when changing lanes or turning. Removing them for aesthetics or easier maneuvering is very dangerous behavior.

Penalty: fine up to 2,000 baht.
