From the Lawrence Daily Journal-World for April 26, 1986:

Gov. John Carlin was expected to sign a controversial proposal requiring Kansas motorists to wear seatbelts. The proposal faced opposition from people who claimed it infringed on personal freedoms and “unfairly intruded into the private lives of the public.” After the House barely passed the bill, 63-62, the 40-member Senate had adopted it, 21-19, despite protests from lobbyists. Some opponents said that the law should not apply to pickup truck drivers, saying that farmers who frequently get in and out of their vehicles should not be required to buckle up. Sen. Robert Frey, R-Liberal, had attempted to strip the bill of its wording on pickup trucks but had failed on a 13-20 vote. The only exemptions in the bill as it stood on this date applied to motorcycles and off-road vehicles, people with medical reasons for not wearing a belt, and mail carriers and newspaper delivery people.
