What is the safest speed to maintain when driving past an emergency vehicle with flashing lights?

When driving past an emergency vehicle with flashing lights, maintaining a speed of 40 km/h is considered the safest choice. This speed is typically lower than the posted speed limit in most areas and allows for reduced stopping distances and better control of the vehicle. It provides drivers with ample time to react to any changes that may occur in the vicinity, such as emergency personnel moving around or needing more space due to the nature of their work.

Driving at this speed also demonstrates respect and caution towards those responding to emergencies, which can be crucial in ensuring the safety of both the emergency personnel and other road users. Additionally, jurisdictions often have specific laws that mandate driving at reduced speeds in such situations, which can help prevent accidents and ensure a safer environment for everyone involved.
