Many of the laws regarding all-terrain vehicle riders in Maine that took effect Sept. 1 are aimed at younger riders. People who violate them are subject to a $100 to $500 fine, unless another amount is indicated.

The new laws:

. Require ATV riders to get oral permission from landowner to use land, except for designated ATV trails and a small amount of state-owned property.

. Require written permission to cross croplands, pastures or orchards.

. Increase fines for failure to stop for a law enforcement agent or eluding a law enforcement officer to a minimum of $1,000.

. Prohibit children less than 10 years old from operating an ATV unaccompanied.

. Prohibit parents, guardians or grandparents from permitting a child under age 10 to operate an ATV unaccompanied off their land.

. Require children ages 10 to 15 to take a training course with their parent, guardian or grandparent in order to operate an ATV unaccompanied.

. Prohibit parents, guardians and grandparents from allowing an unaccompanied person ages 10 to 15 to operate an ATV off their land, unless they have taken a training course.

. Prohibit children less than 16 years old from crossing roads unless the children are between 10 and 15 years and have taken a safety course.

. Prohibit riding at any time of the year on a salt marsh, intertidal zone, marine sand beach, sand dune or a cemetery.

. Prohibit riding, unless the ground is frozen, on alpine tundra, a freshwater marsh or bog, river, brooks, stream, great pond or nonforested wetland or vernal pool or water sources used for consumption. These restrictions do not apply to ATV-

designated trails.

Additional penalties:

. Mandate suspension of Department of Inland Fisheries and Wildlife licenses and permits (such as those for hunting, fishing or trapping) for violations that include operating an ATV on a closed trail or without landowner permission, abusing another person’s property, operating to endanger, reckless operation, failure to stop for or eluding law enforcement and operating while under the influence of intoxicants.
