How far ahead should you place your warning devices on a two-way street?

When you are required to place warning devices on a two-way street following a situation such as a vehicle breakdown or any other roadside emergency, the correct guidance is to place these warning devices at least 100 feet ahead of your vehicle. This distance allows drivers approaching the scene enough time to notice the warning and take appropriate action, such as slowing down or changing lanes, to ensure everyone's safety.

By positioning the devices at the recommended distance, you provide a clear visual cue to oncoming traffic about the potential hazard ahead. The 100 feet requirement is based on ensuring visibility and reaction time, making it an effective practice for minimizing accidents and ensuring the safety of all road users.
