Allowing a 13-year-old to drive a dirt bike alone on the street is generally not legal in most jurisdictions. Laws regarding the minimum age for operating motorized vehicles vary by country and sometimes even by state or province within a country. In many places, a person must be a certain age, typically 16 or 18 years old, to legally operate a motor vehicle on public roads.
There could be several reasons why a 13-year-old might be driving a dirt bike alone on the street, despite it being illegal. These reasons may include:
Lack of awareness: The child or their parents may not be aware of the specific legal requirements or restrictions regarding dirt bike use on public roads.
Parental permission: In some cases, parents may permit their child to ride a dirt bike on the street without realizing it is against the law.
Lack of enforcement: Law enforcement authorities may not always be able to monitor and enforce every instance of illegal dirt bike usage on public roads.
Individual circumstances: There could be unique circumstances where a local law or special permission allows for the operation of motorized vehicles by minors.
