Visibility

• The two-wheeled, tiny vehicle that is the moped is often very difficult for car drivers to see.
  
  

Single-Vehicle Accidents

• It is easier to have a single-vehicle accident with a moped because accidents can occur not only from collisions with other objects but also simply from falling over, given the moped's inherent instability.
  
  

Licensing

• Many states do not require a moped- or motorcycle-specific license to ride a moped, meaning that many people who ride them may be ill equipped for the peculiarities of the moped.
  
  

Speed

• Mopeds are generally able to attain top speeds of only 25 or 30 miles per hour. This means that, although mopeds may try to act like cars, they will almost always be at a disadvantage when it comes to keeping up with the flow of traffic.
  
  

Lack of Protection

• Like motorcycles, mopeds lack the protective structure of a car--doors, windshield, windows, seatbelts and airbags. Riding essentially in the open air leaves the body completely exposed and more prone to serious injury if an accident does occur.
