(AP) — Louisiana lawmakers agreed to stiffen the penalty for drivers who refuse to submit to a breathalyzer test when they are stopped on suspicion of drunken driving, sending the bill Wednesday to Gov. Bobby Jindal, who is expected to sign it. Under current law, a suspect who refuses to take the test loses his driver’s license for six months. The bill that won final passage with a unanimous vote of the House would increase the suspension to one year. If a person refused the test more than once in a five-year period, the driver’s license would be suspended for two years. Supporters of the measure by Rep. Damon Baldone, D-Houma, said the current law seems to encourage the refusal to submit to the test. Opponents had previously argued the proposal was too harsh, but even tougher penalties were lessened by the Senate. Jindal supported the measure as part of his legislative agenda. The changes would take effect Sept. 1. Baldone’s bill also would remove the possibility of a hardship license, for a person to drive to work and school, if the refusal to submit to the breathalyzer test came after an accident that killed or injured someone.
