The Department of Motor Vehicles is launching a new computer system but it may mean some temporary inconvenience for some Rhode Island residents.

Starting today and through July 17, the DMV will only be accepting customers who made reservations in advance. That's to give staff time to get used to the new $19 million system.

Customers arriving at department offices should either print out a confirmation of their reservation with a bar code, or have it available on their phone.

No one will be allowed into a DMV office without a reservation during this period.

To help ease the transition, the agency is extending July expiration dates for licenses and registrations until September, and also extending temporary license plates from 20 days to 40 days.
