Final answer:
Flares should be placed on the right side of the straight road, starting at least 100 feet away from the incident and spaced about 30 feet apart. They should be arranged in a straight line, parallel to the road, and not too close to any obstacles or debris.
Step-by-step explanation:
The proper placement of flares on a straight road is an important safety measure in case of an accident or emergency. Flares are typically placed on the right side of the road, starting at least 100 feet away from the incident and then spaced about 30 feet apart.
This helps to warn other drivers of the potential hazard ahead and gives them time to slow down and proceed with caution.
Placing flares on the right side of the road is crucial because it alerts drivers from the same direction as the incident and provides a clear path for emergency vehicles to pass on the left side of the road.
Additionally, flares should always be arranged in a straight line, parallel to the road, and not too close to any obstacles or debris. This ensures that they can be easily seen by other drivers and minimize the risk of accidents.
