Final answer:
To operate a motorcycle or moped on public roads, one must be of legal age to obtain a license, which varies by location, and should know local traffic laws including pedestrian safety rules based on vehicle speeds.
Step-by-step explanation:
The minimum age requirement to operate a motorcycle or moped on public roads can vary by jurisdiction, but typically one must be of legal age to obtain a motorcycle license or permit. The requirements for obtaining a motorcycle license includes passing a written test on traffic laws and rules of the road for motorcycle riders, and a skills test on motorcycle operation. To ensure safety on the road, it's also important to understand local traffic laws, such as the speed limits, and pedestrian safety measures such as the distance needed to cross a road safely given the speed of oncoming vehicles. For instance, in towns and cities with a speed limit of 60 km/hr, it is essential to cross the road safely by being able to walk at least 4 meters (which is 2 meters further than the width of an average car) before an oncoming car that is at the legal speed limit reaches you.
