What Is the 51/2-a Traffic Fine and Who Does It Apply To?

The 51/2-a traffic fine is a traffic sanction imposed on drivers who exceed the speed limit determined within a built-up area by the amounts stipulated in the legislation. With the regulation that came into force in 2026, speeding violations are classified according to how many km/h the speed limit is exceeded, rather than by what percentage the limit is exceeded. The fine applicable under 51/2-a also varies depending on the amount of the excess speed. Following speed limits is important not only to avoid financial penalties but also to maintain driving safety.

What Is the 51/2-a Traffic Fine?

In its simplest terms, an administrative fine is imposed on a driver when the speed limit determined within a built-up area is exceeded beyond the permitted tolerance.

The traffic regulation that entered into force on February 27, 2026 introduced a tiered structure for the 51/2-a traffic fine. Under the current system, speeding violations within built-up areas are classified between 51/2-a-1 and 51/2-a-9. Each subparagraph provides for a different sanction depending on how many km/h the speed limit is exceeded. Percentage-based speeding violation expressions found in older sources, such as 10% or 30%, are no longer up to date as of 2026, as they have been replaced by kilometer-based calculations.

For Which Speeding Violations Does the 51/2-a Traffic Fine Apply?

The 51/2-a traffic fine applies when the designated speed limit within a built-up area is exceeded by specified amounts. Speed measurements may be carried out by radar, electronic enforcement systems, or other technical methods permitted under the legislation.

According to the 2026 Traffic Administrative Fine Guide, exceeding the speed limit within a built-up area by 6-10 km/h is assessed under 51/2-a-1, exceeding it by 11-15 km/h under 51/2-a-2, and exceeding it by 16-20 km/h under 51/2-a-3. Exceeding the limit by 21-25 km/h falls under 51/2-a-4, 26-35 km/h under 51/2-a-5, and 36-45 km/h under 51/2-a-6.

Sanctions become more severe for higher speeding violations. Exceeding the limit by 46-55 km/h is subject to 51/2-a-7, 56-65 km/h to 51/2-a-8, and 66 km/h or more to 51/2-a-9. When assessing the violation, both the vehicle's measured speed and the applicable speed limit on the relevant road are taken into consideration.

For example, on a road within a built-up area where the speed limit is 50 km/h, a driver detected traveling at 58 km/h has exceeded the limit by 8 km/h. Under the current classification, the violation is assessed under 51/2-a-1. Which subparagraph of the 51/2-a traffic fine applies is determined based on the difference above the speed limit.

How Much Is the 51/2-a Traffic Fine in 2026?

With the new traffic legislation that entered into force in 2026, the 51/2-a traffic fine is not applied as a single fixed amount. Depending on how many km/h the speed limit within a built-up area is exceeded, administrative fines range from TRY 2,000 to TRY 30,000. As the amount of excess speed increases, the applicable sanctions and fine amounts also become progressively more severe.

The current fine amounts, discounted payment amounts, and additional sanctions according to the levels of violation are as follows:

As shown in the table, particularly for serious speeding violations of 46 km/h or more, not only a financial penalty but also a temporary suspension of the driver's licence comes into effect. Complying with speed limits is critically important to avoid facing high fines and the risk of losing your driving licence.

Is There an Early Payment Discount for the 51/2-a Traffic Fine?

A 25% early payment discount can be applied to administrative fines for 51/2-a violations. Under the Misdemeanors Law, unless a different period is prescribed by law, the payment period is one month from the date of notification.

For example, a TRY 2,000 51/2-a fine is reduced to TRY 1,500 with the discount, a TRY 4,000 fine is reduced to TRY 3,000, and the discounted amount for the highest level of TRY 30,000 is TRY 22,500. Making an early payment does not eliminate your right to challenge the fine. The payment and objection processes should be considered separately.

Are Penalty Points Applied to the 51/2-a Traffic Fine?

Drivers who violate the speed limit under Article 51/2-a receive 10 penalty points on their driving licence. In addition to the fine and points, if this violation is repeated 5 times within the previous 1 year, the driving licence is subject to temporary withdrawal.

In this context, when the violation occurs for the 5th time within 1 year, the driving licence is withdrawn for 30 days for an excess of 46-55 km/h, 60 days for an excess of 56-65 km/h, and 90 days for an excess of 66 km/h or more, depending on the amount of excess speed, and all administrative fines must have been paid for the licence to be returned.

How Can You Object to a 51/2-a Traffic Fine?

If you believe that a 51/2-a traffic fine involves an incorrect determination, a licence plate discrepancy, an issue with the measurement, or a problem with notification, it may be subject to legal challenge. Under the Misdemeanors Law, an application may be filed with the Criminal Court of Peace within 15 days from the date of notification or service of the administrative sanction decision.

When preparing an objection, it is useful to consider the fine report, notification document, and records supporting your claim together. Vehicle location records, documents relating to the incident, or documents supporting a material error concerning the licence plate may be important depending on the specific circumstances. If the application period for a 51/2-a traffic fine is missed, the administrative sanction decision generally becomes final. Exceptions regulated by law, such as force majeure, are assessed separately.

It should not be assumed that every traffic fine will be cancelled upon objection. An objection to a 51/2-a traffic fine should be based on the claim that the fine is unlawful in the specific circumstances. It is advisable to check the information contained in the notification and the current legal deadlines before proceeding.

What Is the Effect of a Speeding Violation on the Driving Licence?

A 51/2-a traffic fine may result in the driving licence being temporarily withdrawn for certain periods in cases of significant speeding. In particular, violations under 51/2-a-7, 51/2-a-8, and 51/2-a-9 involve a temporary withdrawal sanction in addition to the monetary fine.

If the driver's licence has been withdrawn five times under Article 51 within the one-year period preceding the date of the most recent violation, additional conditions apply after the fifth withdrawal period ends. The driver must undergo a psychotechnical assessment and an examination by a psychiatrist. If it is determined that there is no condition preventing the person from driving, the licence may be returned. In terms of the 51/2-a traffic fine, it is important to know that repeatedly exceeding the speed limit does not result only in financial consequences.

Who Is the 51/2-a Traffic Fine Applied to in a Rental Vehicle?

A 51/2-a traffic fine may also have consequences for the driver when a speeding violation is committed in a rental vehicle. Under the current regulation, if it can be determined through law enforcement systems that the vehicle was rented at the time of the violation and the renter's address suitable for notification is available, the administrative fine may be issued in the renter's name.

When driving a rental vehicle, speed limits, fixed radar points, and traffic signs on the road apply in the same way. The fact that the vehicle does not belong to you does not eliminate your responsibility regarding speed regulations in terms of the 51/2-a traffic fine. When driving a rental vehicle, getting accustomed to the vehicle's operating characteristics and regularly monitoring the speedometer are important for safe driving.

Have a Safer Journey by Following Speed Limits

The 51/2-a traffic fine contains tiered sanctions aimed particularly at preventing speeding within built-up areas. Monitoring the speed limit throughout your journey, paying attention to traffic signs, and adjusting your driving speed according to road conditions can reduce both the risk of penalties and safety risks. Since fine amounts and sanctions may change over time, it is also important to check current official sources.
