DES MOINES, Iowa (AP) – Few drivers are receiving the tough penalties Iowa lawmakers approved in 2012 for illegally passing school buses when they are stopped.
The Des Moines Register reports that the number of people charged with violating the school bus law has declined, and the law’s tough penalties may make prosecutors more willing to accept lesser charges.

The law calls for a 30-day license suspension for a first offense, costly fines and expensive high-risk insurance. The measure was prompted by the 2011 death of 7-year-old Kadyn Halverson.

The number of drivers charged with illegally passing a bus fell to 895 in 2015 from 1,030 in 2012. Authorities say part of the problem is that the bus driver or another driver is often the only witness, so it can be difficult to prove.
