A proposal would allow Michigan police to use new, portable drug testing kits when they suspect a motorist is under the influence of substances other than alcohol.
Legislation to allow the roadside drug tests was introduced Wednesday in the state House.
The bills would create guidelines for using a preliminary oral drug test during a traffic stop. Republican state Rep. Rick Jones of Grand Ledge says police could know within minutes whether a driver is high on drugs, similar to tests for alcohol that have been given at roadside traffic stops for years.
Jones said the new drug test could replace more time-consuming measures now in use such as getting warrants to allow blood tests.
Jones said Michigan police could be the first to use the kit.
