The strategy that would best reduce the risk of automobile accidents is B. Obeying traffic laws.
Obeying traffic laws involves following speed limits, stopping at red lights and stop signs, yielding the right of way, using turn signals, and other rules and regulations that promote safe driving practices. By adhering to traffic laws, drivers can minimize the likelihood of collisions and maintain a safer driving environment for themselves and others on the road.
Engaging in a strict exercise regimen (option A) may contribute to overall physical fitness but does not directly address the risk of automobile accidents.
Texting while driving (option C) is extremely dangerous and significantly increases the risk of accidents. It is illegal in many jurisdictions and strongly discouraged as it diverts attention from the road.
Adding comprehensive auto insurance (option D) is a responsible step to protect against financial loss in the event of an accident, but it does not directly reduce the risk of accidents. It provides coverage for damages and liabilities after an accident has occurred.
