S.F. 2116 the explanation’s substance by the members of the general assembly. 1 This bill repeals and replaces provisions regulating driving 2 on the right side of roadways and overtaking and passing on 3 roadways. 4 The current driving requirements and prohibitions found in 5 Code sections 321.297, 321.298, 321.299, 321.302, 321.303, 6 321.304, and 321.306 remain in effect with certain changes. 7 The bill distinguishes roadways in two ways: (1) roadways 8 not laned for traffic or laned for traffic in opposing 9 directions and (2) roadways laned for traffic moving in the 10 same direction. 11 The bill requires a person to drive in the right-hand lane 12 on a roadway with multiple lanes for traffic moving in the 13 same direction or to the right of the center line of any other 14 roadway, as applicable. Limited exceptions include while 15 overtaking another vehicle and avoiding obstructions when such 16 actions can be completed safely, while authorized by official 17 traffic-control devices, and while preparing to make a left 18 turn, so long as the driver yields to all vehicles traveling 19 in the proper direction. However, if the roadway has three or 20 more lanes for traffic moving in the same direction, a driver 21 is required to drive in the center lanes, such that the far 22 left lane can be used for overtaking and the far right lane can 23 be used to enter or exit the roadway, as applicable. 24 The bill also provides for these traffic regulations and 25 prohibitions, as applicable, on one-way roads, roads with 26 temporary passing lanes, and roads with center turn lanes. 27 Overtaking another vehicle is only authorized when such 28 action can be completed safely and without causing another 29 vehicle to adjust speed or direction. The authorized manner 30 for and prohibitions against overtaking another vehicle remain 31 similar to current law. 32 A person who violates the bill is guilty of a simple 33 misdemeanor punishable by a scheduled fine of $135, which 34 matches the current penalty for such violations. However, a 35 -6- LSB 5562SV (1) 90 th/ns 6/ 7

S.F. 2116 peace officer is required to issue a warning memorandum in lieu 1 of a citation until July 1, 2025, to a person who drives in 2 the left lane of a roadway with two lanes for traffic moving 3 in the same direction when an exception does not apply, and 4 to a person who drives in either the left or right lane on a 5 roadway with three or more lanes for traffic moving in the same 6 direction when an exception does not apply. 7 Similar to current law, if a violation of the bill causes a 8 serious injury, a court could impose an additional fine of $500 9 or suspend the person’s driver’s license for not more than 90 10 days, or both. If the violation causes a death, a court could 11 impose an additional fine of $1,000 or suspend the person’s 12 driver’s license for not more than 180 days, or both (Code 13 section 321.482A). 14 -7- LSB 5562SV (1) 90 th/ns 7/ 7
