3. Which method of patrol is an effective form of traffic enforcement? A. Motorcycle patrol B. Aircraft patrol C. Foot patrol D. Bicycle patrol

The correct answer is A. Motorcycle patrol.<br /><br />Motorcycle patrol is an effective form of traffic enforcement because it allows law enforcement officers to travel at high speeds and navigate through traffic congestion more easily than other patrol vehicles. Motorcycles are also more maneuverable and can be used to intercept speeding vehicles or pursue suspects. Additionally, motorcycle patrol officers can serve as a deterrent to reckless driving and can respond quickly to incidents in the field.
