BOISE, Idaho (AP) — Driverless cars are one step closer to joining Idaho citizens on the roads.

By a one vote margin, the Idaho Senate passed a bill allowing companies to test self-driving cars in Idaho. The bill also sets some regulations and guidelines aiming to improve safety. Senate Transportation Committee Chairman Sen. Bert Brackett told lawmakers Thursday he hopes the bill will attract innovative businesses to Idaho.

But the plan's insurance and liability requirements faced bipartisan opposition on the floor. Senate Majority Leader Bart Davis, who voted no, says the plan shouldn't put all the responsibility for damage on the testing company, while absolving manufacturers. Democratic Sen. Grant Burgoyne from Boise says the bill's $1 million insurance policy requirement is too low. The bill now goes to the House for approval.
