S.F. _____ This bill amends Code section 321.306, which contains 1 requirements for driving a vehicle on roadways laned for 2 traffic. Currently, the requirement to drive as nearly as 3 practical entirely within a single lane is combined with the 4 requirement not to move from the lane until the driver has 5 first ascertained that the movement can be made safely. The 6 bill separates those two requirements and makes semantic 7 changes to the language of the Code section. 8 Pursuant to current law, a violation of the requirements of 9 Code section 321.306 is a simple misdemeanor, punishable by a 10 scheduled fine of $100. A violation that causes serious injury 11 to or the death of a person may be subject to an additional fine 12 and driver’s license suspension. 13 -2- LSB 5707SC (2) 85 dea/nh 2/ 2
