When should you pull over for an emergency vehicle if you have not entered the roundabout?

When you encounter an emergency vehicle while still outside of a roundabout, the appropriate action is to pull over to the side of the road and allow the emergency vehicle to pass. This is important for several reasons. Firstly, doing so ensures that the emergency vehicle can navigate through traffic without delay, which is critical when responding to urgent situations. Additionally, it promotes safety for all road users, as it reduces the risk of collisions that could occur if vehicles remain stationary or try to maneuver inappropriately within traffic lanes.

It's also worth noting that simply stopping in your current lane could create an obstruction for both the emergency vehicle and other drivers. Waiting until the emergency vehicle passes could lead to unnecessary delays and hinder their response. Taking the next exit might not be a feasible option, especially if you are not close to an exit, thus making it impractical. Therefore, safely pulling over is the best choice to ensure the emergency vehicle can proceed quickly and efficiently.
