Japan vs Turkey: Driving Rules Compared

Turkey rebuilt its speeding fine system in 2026, moving from percentage-based penalties to nine fixed km/h tiers that start fining drivers just 6 km/h over the limit inside towns. Japan keeps a simpler flat structure, moving from JPY 9,000 up to JPY 25,000 or more as the overage grows. The road itself flips too: Japan drives on the left, Turkey on the right.

Japan drives on the left while Turkey drives on the right. This is one of the most significant adjustments drivers must make when travelling between these two countries. Take extra care at junctions, roundabouts, and when overtaking.

Speed Limits Comparison

One of the most practical differences for drivers is the variation in speed limits between Japan and Turkey.

Japan sets its speed limits at 40 km/h in cities and towns, 60 km/h on country roads, and 100 km/h (100 km/h standard; 120 km/h on select expressway sections (Shin-Tomei, Tohoku, Joban). From Sept 2026, narrow residential roads default to 30 km/h) on motorways.

Turkey sets its speed limits at 50 km/h in cities and towns, 90 km/h on country roads, and 120 km/h on motorways.

Key Speed Limit Differences

Always check posted speed signs when crossing between Japan and Turkey. Relying on your knowledge of one country’s limits while driving in the other is a common cause of speeding fines for tourists.

Traffic Rules and Regulations

Beyond speed limits, Japan and Turkey have several important differences in their general traffic rules.

Driving side: Japan drives on the left; Turkey drives on the right. This is a major difference that requires careful adjustment.

Minimum driving age: The minimum age to drive a car is 18 in Japan and 18 in Turkey.

Mobile phone use: Using a handheld mobile phone while driving is illegal in both countries. In Japan, the penalty is JPY 18,000 (approx. EUR 115) + 3 points. In Turkey, the penalty is TRY 5,000 (approx. EUR 130). Hands-free devices are generally permitted in both countries, but drivers should keep their attention on the road.

Seatbelts: Seatbelts are mandatory for all occupants in both Japan and Turkey. The fine for not wearing a seatbelt is Warning / 1 point (no fine for first offence) in Japan and TRY 2,500 (approx. EUR 65) in Turkey.

Running a red light: Red-light violations carry serious penalties. In Japan, expect JPY 9,000 (approx. EUR 55) + 2 points. In Turkey, the penalty is TRY 5,000 (approx. EUR 130).

Alcohol and DUI Laws

Alcohol and driving regulations differ between Japan and Turkey, and the penalties for non-compliance can be severe in both.

Japan sets its blood alcohol concentration (BAC) limit at 0.03%.

Turkey has a BAC limit of 0.05%.

The lower limit in Japan means that even a small amount of alcohol could put you over the legal limit. Adjust your behaviour accordingly.

In both countries, penalties for drink-driving include fines, licence suspension, and potential imprisonment for serious offences. New and young drivers often face stricter limits (typically 0.00% to 0.02% BAC) in both Japan and Turkey. The safest approach is always to avoid any alcohol before driving.

Tyre and Equipment Requirements

Tyre regulations and mandatory vehicle equipment differ between Japan and Turkey, and non-compliance can result in fines, especially during winter.

Winter Tyres

• Japan: Winter tyres are situational. Period: Prefectural regulations; Hokkaido, Tohoku require winter tyres in winter. Studded tyres: restricted. Minimum tread depth: 1.6 mm.
• Turkey: Winter tyres are situational. Period: 15 Nov - 15 Apr (commercial vehicles mandatory; passenger cars situational). Studded tyres: prohibited. Minimum tread depth: 1.6 mm.

Mandatory Equipment

Rental vehicles usually come equipped for the country of hire. If you intend to drive in both Japan and Turkey, check with the rental company that the vehicle has all required items for both destinations.

Speeding Penalties

The financial consequences of speeding vary between Japan and Turkey.

In Japan, a minor speeding offence (approximately 10 km/h over the limit) typically results in: JPY 9,000 (approx. EUR 55) + 1 point. Penalties escalate significantly for higher speeds, and repeat offenders face licence suspension.

In Turkey, a minor speeding offence (approximately 10 km/h over the limit) typically results in: TRY 2,000 (approx. EUR 50). Penalties escalate significantly for higher speeds, and repeat offenders face licence suspension.

Both countries use a combination of fixed speed cameras, mobile speed traps, and in some cases average speed (section control) cameras.

Licence Requirements for Visitors

Licence requirements for foreign visitors differ between {a} and {b}. Here is what you need to know.

Japan: An IDP is required. Visitors can typically drive for up to 12 months on a foreign licence IDP required (1949 Geneva Convention only). US, UK and many EU licences need specific IDP. Drives on the left.

Turkey: An EU/EEA driving licence is valid. An IDP is required for non-EU licence holders. Visitors can typically drive for up to 6 months on a foreign licence IDP required for most foreign visitors. EU licences accepted for 6 months.

Always carry your licence (and IDP if applicable) while driving, as police may request to see it during routine checks or traffic stops.

Emergency Numbers

In case of an emergency while driving, it is essential to know the local numbers:

Save these numbers in your phone before travelling. In an emergency, quick access to the correct number is crucial.

Practical Tips for Driving in Both Countries

If you are planning to drive in both Japan and Turkey, here are some practical tips to keep in mind:

1. Use a GPS or navigation app. Modern navigation apps often include speed limit warnings, toll information, and real-time traffic updates that can help you comply with local rules.

2. Learn key phrases. If you do not speak the local language, learn basic driving-related phrases. In an emergency, being able to communicate with police or paramedics can be invaluable.

3. Carry the right documents. Ensure you have your driving licence, IDP (if needed), vehicle registration, and insurance documents. Some countries require you to carry these at all times.

4. Research before you go. Familiarise yourself with the specific rules of each country before your trip. Print or save a summary of key rules for quick reference.

5. Adjust to speed limits immediately. When crossing the border, speed limits change. Look for signs and adjust your driving accordingly. Do not rely on habits from the other country.

6. Watch for different road signs. While European countries share many sign conventions, there are country-specific signs you should recognise. Review a local driving guide before your trip.

7. Understand toll systems. Research whether you need a vignette, transponder, or cash for tolls in each country.

8. Plan fuel stops. Fuel prices and station availability can vary significantly. In some regions, stations may close at night or on Sundays.

Which Country Is Easier for Tourists to Drive In?

For most international tourists, the overall driving experience will vary based on road conditions, signage clarity, and traffic density.

Based on tourist ratings, Japan scores 3.0/5 (Moderate). Left-hand driving, expensive tolls, excellent roads, kanji signage

Based on tourist ratings, Turkey scores 3.6/5 (Challenging). Aggressive driving culture, variable road quality, Istanbul traffic extreme

The switch between left-hand traffic in Japan and right-hand traffic in Turkey is the single biggest adjustment drivers will face.
