What should you use when parked on the side of the road?

Using four-way flashers when parked on the side of the road is crucial for alerting other drivers to your presence. This is particularly important in situations where visibility may be limited or when your vehicle is situated in such a way that it could pose a hazard to moving traffic. Activating your four-way flashers makes your vehicle more noticeable, thereby enhancing safety for both you and passing motorists.

While hazard cones help mark your vehicle's position as a warning to others, they are not always practical in every scenario. Headlights can also be useful, but they don’t convey the same alertness of a stationary vehicle that you get from four-way flashers. The parking brake is essential for ensuring that the vehicle remains stationary and does not roll, but it does not provide any warning to other drivers. Therefore, the use of four-way flashers is the most effective way to communicate that your vehicle is parked on the side of the road.
