Do you want to know the most important rule for driving in tunnels? Simply follow the normal rules of the road. Many locations across North America are filled with short and long tunnels that pass through mountains and under rivers. Although tunnels can be stressful for a first-time car rental customer, they don't need to be. While there are some guidelines you should take into consideration, for the most part, driving in a tunnel is much like driving on the open road.
Be Aware As You Approach
As you approach any tunnel in your car rental, pay close attention to your vehicle, road signs, and other traffic. Signs may warn of height restrictions, speed limits, lane closures and tunnel length. Check your vehicle's gauges to be sure it is running at normal temperature, no warning lights are illuminated, and you have sufficient gas. Breaking down inside a tunnel is a safety risk and will cause long delays. As you enter, switch on your low beams to help light up the road, and remove sunglasses if you are wearing any.
Use Extra Caution Inside
Although the road conditions will likely be clear and dry in the tunnel, leave extra space between your rental car and the vehicle in front of you, especially if the tunnel curves. Obey all signs including speed limits and passing restrictions. U-turns are often illegal and dangerous in tunnels. Once you've entered, continue moving unless the flow of traffic stops. If traffic slows to a near stop, turn on your four-way hazard lights to alert the vehicle behind you. If traffic stops completely, stay in your vehicle and leave at least one car length of space ahead of you.
Stay Calm in an Emergency
If you witness an accident or any other emergency situation, stay calm. Tunnels where both ends are not visible are typically equipped with emergency features. As you drive through, make a mental note of emergency exits, phones, and alarms. Remember: your cellphone will likely lose reception in the tunnel, so it's important to note alternative safety measures. If you are forced to leave your vehicle, be aware of oncoming traffic, as flow may have only stopped in one direction. Driving through a tunnel is typically a stress-free event — simply follow the rules, pay extra attention to signs, and exercise caution.
Before entering a tunnel, ensure your vehicle is running well, your headlights are on, and you have sufficient fuel. A few moments of preparation can prevent a dangerous situation inside.
