Rep. Eleanor Holmes Norton, D-D.C., is demanding that an electric scooters ban on Capitol Hill be reversed, Roll Call reported.

Holmes Norton sent a letter to Capitol Police Chief Steven Sund Tuesday arguing that scooters are an “affordable, environmentally friendly and efficient mode of transportation” relied upon by an increasing number of Hill staffers, D.C. residents and visitors, Roll Call reported. Capitol police announced a ban on scooters on the grounds of the Hill in May, citing a traffic law that regulates “skating and play vehicles” on the grounds of the Capitol.

“Electric scooters should be treated like motorized bicycles, mopeds, segways and the other low-speed vehicles,” Holmes Norton wrote to D.C. police.

Holmes Norton said the traffic law should not apply to scooters because they are considered by police as “low speed vehicles” that are not allowed to be parked on sidewalks or against buildings. Scooters are also not used as toys, she said.

Capitol Police spokeswoman Evi Malecki told Roll Call in May, the month the scooter ban went into effect, that the increase in electric scooters for rent “has become a safety and security concern for the department.” She said electric scooters should not be parked or left unattended on the grounds of the Hill.

Holmes Norton requested a response to her letter within 30 days.
