How far from a scene should an officer ideally place the first flare for a car traveling at 60 mph?

When determining how far from a scene of an accident to place the first flare for a car traveling at 60 mph, it's essential to consider the stopping distance and reaction time of approaching vehicles. The National Highway Traffic Safety Administration (NHTSA) recommends placing flares or warning devices at a distance that allows oncoming traffic ample warning to slow down or change lanes, ensuring safety for both responders and motorists.

For a vehicle going at 60 mph, it can travel a significant distance in a short amount of time. Typically, the stopping distance for a vehicle traveling at 60 mph can be around 180 to 250 feet, factoring in perception and reaction time. Hence, placing a flare at approximately 200 feet provides an adequate buffer, giving drivers enough time to recognize the hazard and respond accordingly.

This distance accounts for an average driver's reaction time and allows for safe navigation around the incident scene. Therefore, positioning the first flare at 200 feet is the most suitable option, balancing visibility, safety, and the practical dynamics of traffic encountering an accident scene.
