______________ Allow Drivers To Pass Other Vehicles.

Passing maneuvers are fundamental to driving, allowing drivers to overtake slower vehicles and maintain a desired speed. Executing these maneuvers safely and effectively requires understanding various factors, including traffic regulations, road conditions, vehicle capabilities, and the behavior of other drivers. Safe passing practices not only improve traffic flow but also significantly reduce the risk of accidents.

Understanding the Basics of Passing

Passing, or overtaking, is the act of one vehicle going around another moving in the same direction. It's a common procedure on two-lane roads where traffic flows in both directions and is crucial for maintaining efficient traffic flow. However, it’s also one of the riskiest maneuvers a driver can perform.

Legal Aspects of Passing

Passing Zones: Marked with broken yellow lines on the driver's side of the road. These lines indicate where it is legal to pass other vehicles.
No-Passing Zones: Indicated by a solid yellow line on the driver's side. These zones are areas where passing is prohibited due to safety concerns, such as curves, hills, or intersections.
State and Local Laws: It's essential to be aware of and comply with state and local laws regarding passing, as regulations can vary.

Risks Associated with Improper Passing

Head-on Collisions: One of the most severe risks, especially on two-lane roads.
