Nicco wrote this rough draft. He wants to revise the draft to include evidence from a credible source.

Young drivers should be required to hold a provisional driver’s license for one year before earning full driving privileges. Provisional licenses have restrictions on the number of passengers allowed in the car. Provisional licenses also restrict the number of hours that drivers can be on the road. These restrictions save lives because newly licensed drivers need time to become comfortable on the road.
