Navigating tunnels and bridges requires strict adherence to safety regulations to prevent accidents and traffic congestion. This article explores the legal requirements for drivers in Turkey, focusing on prohibitions and correct behaviors that frequently appear in the MTSK e-sınav. By mastering these rules, you will be prepared to answer situational questions about restricted road zones and improve your overall traffic safety knowledge.

Article content overview
Navigating high-risk infrastructure like tunnels and bridges is a fundamental competency required for every driver in Turkey. These environments present unique hazards, ranging from limited visibility and confined spaces to restricted airflow and complex exit geometries. For candidates preparing for the MTSK e-sınav, understanding the specific legal prohibitions associated with these zones is not just about passing the theory test—it is a critical requirement for ensuring road safety during your future driving experience.
In the Turkish Road Traffic Regulations, tunnels and bridges are classified as sensitive zones where specific maneuvers are strictly forbidden to maintain traffic flow and prevent catastrophic accidents. Failing to grasp these concepts can lead to significant point deductions on your theoretical exam, as questions often focus on the driver’s ability to recognize and avoid dangerous behaviors in these sections.
The most important rule to remember for the MTSK exam is that stopping, parking, and making U-turns within tunnel and bridge zones are categorically prohibited. Because these areas often lack a wide shoulder or emergency lane, any stopped vehicle becomes an immediate, high-speed hazard for following traffic. If your vehicle breaks down while inside a tunnel or on a bridge, you must attempt to move it to the nearest designated emergency bay or exit point immediately.
In the context of the Turkish theory test, always remember that you are strictly forbidden from changing lanes inside tunnels or on bridges unless marked otherwise by specific road signs or overhead lane control signals. This is a common trap in exam scenarios; even if the traffic is slow, you must maintain your lane discipline until you are clear of the restricted area.
Visibility is a significant safety factor when entering tunnels. Even during daylight hours, the human eye requires time to adjust to the sudden shift in lighting levels. Turkish traffic law requires drivers to switch on their low-beam headlights before entering a tunnel, regardless of the time of day, to increase the vehicle’s visibility to others and ensure the driver can perceive the road markings and potential obstructions clearly.
Speed limits in tunnels and on bridges are often lower than on the open highway due to the lack of "escape space." When you encounter questions regarding speed in these areas, always prioritize the specific speed limits indicated by road signs over the general motorway speed limit. Furthermore, because of the increased risk of chain-reaction collisions in confined spaces, maintaining an adequate following distance is legally and practically essential.
The distance in meters that must be maintained behind the vehicle in front, which should generally be equivalent to at least half of your current speed in kilometers per hour. In tunnels, it is highly recommended to increase this gap to account for reduced reaction time.
| Maneuver | Status in Tunnel/Bridge | Consequence |
|---|---|---|
| U-Turn | Prohibited | High collision risk; legal penalty |
| Overtaking | Prohibited | Illegal in single-tube or narrow sections |
| Stopping | Prohibited | Only allowed in case of emergency |
| Lane Change | Restricted | Illegal across solid lines |
The MTSK e-sınav often presents scenario-based questions about tunnel transit. You might be asked how to react if a vehicle in front of you suddenly slows down or if you notice smoke inside a tunnel. The expected answer always emphasizes calmness, maintaining your lane, and immediately activating hazard warning lights to alert vehicles behind you if you are forced to slow down significantly or come to a halt.
Tunnels and bridges are high-risk zones under Turkish Road Traffic Regulations where specific maneuvers are strictly forbidden to prevent accidents and maintain traffic flow. The most critical prohibitions include stopping, parking, U-turns, and lane changes across solid lines, with the only exception being when directed by official road signs or signals. Drivers must activate low-beam headlights before entering any tunnel and maintain increased following distances due to confined spaces and reduced escape options. If a breakdown occurs, the priority is to reach the nearest emergency bay or exit while activating hazard lights. For the MTSK e-sınav, expect scenario-based questions about emergency response procedures and recognizing which maneuvers are illegal in these restricted zones.
A short set of high-value points that capture the most important ideas from this article.
Stopping, parking, and making U-turns are categorically prohibited inside tunnels and on bridges in Turkey.
Low-beam headlights must be switched on before entering any tunnel, regardless of time of day.
Lane changes inside tunnels and on bridges are illegal unless specifically indicated by road signs or overhead signals.
If your vehicle breaks down in a tunnel or on a bridge, immediately move it to the nearest emergency bay or exit point.
Speed limits in tunnels and on bridges are lower than open highway limits and must be followed as indicated by signs.
In tunnels, increase your following distance to account for reduced reaction time—generally half your speed in km/h as a minimum baseline.
During a tunnel emergency, activate hazard warning lights immediately, switch off the engine if stopped for extended periods, and follow overhead digital signage instructions.
Overtaking is prohibited in single-tube or narrow tunnel sections.
Do not exit your vehicle inside a tunnel unless absolutely safe to do so.
Emergency lanes (Emniyet Şeridi) are strictly for disabled vehicles and official use only.
Assuming lane changes are permissible if traffic is slow—solid lane lines inside tunnels make this illegal regardless of congestion.
Forgetting to turn on headlights before entering a tunnel because it appears bright outside.
Attempting to stop or park briefly on a bridge shoulder, which is prohibited and creates high-speed hazards.
Panicking during a tunnel emergency instead of following the systematic procedure (hazard lights → engine off → stay in vehicle → follow signage).
Confusing general motorway speed limits with tunnel-specific limits, which are typically lower.

No. According to Turkish Road Traffic Regulations, stopping, parking, or making a U-turn in tunnels is strictly prohibited unless there is an emergency or a breakdown.
Generally, lane changes are prohibited in tunnels unless indicated by road markings or signs. Drivers should maintain their lane to ensure safe traffic flow and minimize the risk of collisions.
If possible, move your vehicle to the designated emergency bay. Turn on your hazard warning lights, turn off the engine, and follow official tunnel safety protocols for evacuation and assistance.
