The Washington State Department of Natural Resources said it will begin enforcing the state’s strict new environmental laws, including the prohibition on ecotours, starting on Tuesday.
The department said that violators face fines of up to $1,500 per day.
It will also enforce new rules on recreational vehicle operation.
The new rules will be implemented in mid-January, the department said.
“It’s not just about getting a ride, it’s about getting out there, getting out of the car and enjoying the environment,” said John Eaves, a spokesman for the department.
“The new rule will make sure that every driver who wants to ride is doing so with the highest possible safety standards.”
Eaves said violators will face a range of fines ranging from $50 to $100 per day, depending on the severity of the violation.
The rule is expected to add $10,000 to the cost of a license plate.
The state has long been one of the country’s most liberal places to ride a bicycle, a perk that has drawn the ire of some environmental groups who say it makes it difficult for cyclists to gain access to green spaces.
