It is against the law to operate a moped on an interstate highway traveling at speeds over what?

Operating a moped on an interstate highway is subject to specific legal restrictions regarding speed. The correct threshold is that it is against the law to operate a moped traveling over 35 mph on an interstate highway. This regulation is in place because mopeds are typically not designed for high-speed travel and may not be able to safely navigate high-traffic areas where vehicles are traveling at much higher speeds.

When mopeds travel at speeds exceeding this limit, they pose a significant risk not only to the rider but also to other drivers, as they may not maintain the necessary speed to keep pace with surrounding traffic safely. Adhering to the 35 mph limit helps ensure the safety of all roadway users and maintains the intended use of interstate highways for faster-moving vehicles. Other speeds mentioned, like 30 mph, 25 mph, or 40 mph, do not represent the legal limit for mopeds on interstates, as 35 mph has been established as the maximum for safe operation.
