Seeing an ambulance with sirens on while driving on the highway at night always requires extra attention for drivers. Factors like limited visibility, high speed, and fatigue create risks in terms of secondary accidents and chain collisions. [1] In this article, we discuss what you need to do to increase safety when you encounter an ambulance on the highway at night and while waiting for an ambulance.
Remember That Night Vision Is Limited
Factors like oncoming headlights, rain, or fog restrict night vision even more. Therefore:
- Keep the following distance longer than during the day. [2]
- Take care to keep your speed at a level suitable for your viewing distance. [2]
- Do not use rear fog lights unnecessarily; do not dazzle drivers coming from behind. [3]
These basic rules are the first steps of night highway safety, whether there is an ambulance or not.
What Should You Do When You Hear an Ambulance Siren at Night?
Instead of braking suddenly as a reflex when you hear a siren sound, follow these steps:
- First listen to the sound and try to understand which direction the ambulance is coming from.
- Determine its position by checking your mirrors.
- Slow down safely and clear the lane you are in to be suitable for the ambulance's passage. [3]
- If possible, contribute to creating a "life corridor" in the middle by pulling over to the right lane. [3]
Sudden braking and sharp maneuvers can endanger both you and the vehicles coming from behind. [2]
