What is a Bridge (Köprü) in Turkish Traffic Law?

In Turkish traffic legislation governed by the General Directorate of Highways (KGM), a bridge (köprü) is defined as any structure designed to carry a roadway over an obstacle such as a river, valley, railway, or another road. This category also includes overpasses, underpasses, and complex viaducts (viyadük). Because bridges represent elevated bottlenecks with limited escape space, they are treated as high-risk zones under Turkish traffic regulations, meaning strict operational rules apply to any driver crossing them.

Key Safety Hazards When Driving on Bridges

Operating a vehicle on a bridge requires heightened situational awareness due to physical and environmental forces that do not affect standard flat roadways:

• Microclimates and Rapid Freezing: One of the most critical hazards taught in Turkish driving theory is that bridge decks freeze much faster than adjacent land-based roads. Because cold air circulates both above and directly underneath the suspended concrete or steel structure, the bridge loses its heat rapidly. This frequently creates highly dangerous, invisible "black ice" even when the approaching highway surface looks completely dry.
• Sudden Crosswinds: Bridges built over large bodies of water or deep valleys are highly exposed to lateral wind gusts. High-profile vehicles, such as vans, trucks, and buses, are particularly vulnerable to being pushed out of their lanes by sudden crosswinds.
• Narrowed Lanes and Lack of Hard Shoulders: Many older bridges do not feature a safety lane or hard shoulder. This means any vehicle breakdown or minor collision immediately creates a severe hazard and blocks traffic flow.

Official Driving Regulations on Turkish Bridges

To ensure traffic safety and prevent catastrophic multi-vehicle accidents, the Turkish Highway Traffic Regulation enforces strict laws on bridges:

• No Stopping or Parking: Stopping, standing, or parking your vehicle on a bridge is strictly illegal under any circumstances except emergency breakdowns.
• No Reversing or U-Turns: It is strictly prohibited to reverse, perform a U-turn, or attempt to turn around on a bridge.
• Overtaking Restrictions: In general, overtaking is prohibited on narrow, two-lane bridges or on approaches to them. Drivers must maintain their lane and follow the vehicle ahead at a safe distance.
• Strict Lane Discipline: Bridges are typically marked with solid single or double white lines. Drivers must select their desired lane before entering the bridge structure and are legally required to maintain that lane until they clear the span.

Understanding Narrow Bridge Priority Rules

On narrow bridges where two vehicles cannot safely pass each other at the same time, specific priority rules apply. On the Turkish driving theory exam, you will often face questions depicting these scenarios.

Normally, traffic signs regulate this priority. The red circular sign "Oncoming Traffic Has Priority" (Karşıdan Gelene Yol Ver) indicates that you must stop and yield to vehicles coming from the opposite direction. Conversely, the blue square sign "Priority Over Oncoming Traffic" (Karşıdan Gelen Araçla Karşılaşmada Geçiş Kolaylığı) gives you the right of way. If no signs are present, drivers must follow the standardized Turkish right-of-way hierarchy for narrow roads, where larger, less maneuverable vehicles are generally yielded to by smaller, more agile vehicles.

Exam Tips: How to Answer Bridge-Related Theory Questions

When preparing for your Turkish driving theory exam (ehliyet sınavı), keep these key test-taking tips in mind:

1. Look for the Wind Sock Sign: If an exam question displays a warning sign with a wind sock near a bridge, the correct answer will always involve reducing speed, gripping the steering wheel firmly with both hands, and avoiding overtaking maneuvers to counter potential crosswinds.
2. Remember the "Freeze First" Rule: If a question asks which road surface is most likely to freeze first during cold weather, the answer is always "Bridges and Viaducts."
3. Assume Overtaking is Forbidden: Unless lane markings explicitly permit it (which is rare), select the option that identifies overtaking on narrow bridges as a traffic violation.
