Lime is reactivating small fleets of scooters in about a dozen cities. It will offer free 30-minute rides for health care workers and law enforcement officers. The lime aid initiative is meant to address essential workers’ need for transportation while social distancing amid the coronavirus pandemic.

Lime will partner with cities to determine the best locations for the scooters. The scooters are meant to be used for essential trips only, such as to the grocery store or doctor’s office, not for joy riding.

The company plans to start lime aid in the first batch of cities. The company says it will expand to other cities in the coming weeks.
