Indiana bill to increase semi truck speed limits faces tough road ahead

A pair of bills filed in the Indiana Legislature seek to raise the speed limit for large trucks on certain state highways and interstates, but continuing pushback from a Hoosier truck drivers group is likely to keep the measures from becoming law.

Five prior proposals to eliminate the lower speed limit for trucks have been filed in the House since 2017 without success. All have been authored by Rep. Mike Aylesworth, R-Hebron, but none have ever received a hearing in committee.

He’s filed the same language in a bill again this year, hoping that it can at least be discussed in the House Roads and Transportation Committee, where it’s been assigned.

“Those of us that live a considerable distance from the state capital travel interstates, and it’s always bothered me that Indiana has a bifurcated speed limit,” Aylesworth told the Indiana Capital Chronicle. “The trucks can be very annoying, going slower than regular traffic. I think for safety sake, they all ought to be uniform.”

Sen. Jim Tomes, R-Wadesville, has authored a separate bill that similarly seeks to increase speed limits for large vehicles, like semi trucks.

Like Aylesworth’s bill, Tomes’ measure would raise the speed limit for trucks to 70 mph on highways and interstates outside urban areas. Currently, those vehicles aren’t supposed to travel faster than 65 mph.

Tomes declined the Indiana Capital Chronicle’s request for comment about the bill.

Increased speed limit would make roads ‘safer’

Under current Indiana law, passenger vehicles are allowed to travel at 70 mph while commercial vehicles (other than buses) weighing more than 26,000 pounds are subject to the reduced speed limit.

There are about 124,000 vehicles that meet this weight criteria registered in Indiana, according to a legislative fiscal report. The Indiana Department of Transportation reported in 2018 that more than 414 million tons of truck freight travels through Indiana each year, making it the fifth busiest state for commercial freight traffic.

Aylesworth said Indiana’s lower speed limit for trucks creates more traffic–and makes roads less safe.

“I was coming back from a trip to South Carolina, and as we came back through the Carolinas and Tennessee and Kentucky—where the speed limits are all the same—we didn’t have many blockages of semis,” he said. “We came to southern Indiana, and all of a sudden, you’ve got semi issues, for stretches, and it’s very aggravating.”

Indiana is one of eight states that require a lower speed limit for semi trucks on rural interstates and highways, according to the Insurance Institute for Highway Safety.

Those in support of the increased speed limit for large trucks maintain that the current split speed creates congestion for surrounding traffic. They further argue that averting trucks can be hazardous—especially on rural roads that are often reduced to two lanes.

Groups like the Owner-Operator Independent Drivers Association, or OOIDA, a national trade union representing professional truck drivers, have opposed different speed limits for heavy-duty trucks “because it decreases safety by increasing the interaction between large trucks and passenger vehicles.”

Motor Truck Association remains opposed

But Aylesworth said years of pushback from the Indiana Motor Truck Association, or IMTA, which represents the trucking industry in the state, has largely kept the bill from even being placed on the committee schedule.

IMTA President and CEO Gary Langston maintains that the group “will continue to support” the current lower speed limit for trucks in Indiana, rather than measures to raise those speeds.

“There are different opinions within the industry, yet the majority of our members continue to support the 65 mph speed limit,” Langston said in a written statement. “As trucks with technological advanced safety features become more prevalent, an increased speed limit may be more acceptable.”

Still, Aylesworth said his conversations with insurance experts, INDOT and the Indiana State Police indicate that “everybody’s cool with it.”

“There isn’t going to be a significant change in accidents or increased danger to the public,” Aylesworth said. “It’s just very frustrating. With the (IMTA) … we have a disagreement on this one.”

In 2020, there were 153 people killed in crashes involving large trucks in Indiana, according to the U.S. Department of Transportation. At least 26 fatal semi-involved crashes in the state involved speeding.

An Indiana Public Policy Institute report also notes that occupants in large trucks were almost five times as likely to be injured in crashes when speeding, compared to the same vehicle type not speeding.

A chance to be heard in the Senate committee?

Aylesworth said he wasn’t sure if his bill would get traction in the House committee in the 2023 session. Anytime he’s told a committee chairperson about the IMTA pushback, he’s been told that he’s “going to have trouble” moving the bill forward.

But given that Tomes is a ranking member of the Senate committee to which his bill has been assigned, it’s possible that his proposal could be up for debate.

Even if Tomes’ bill makes it out of the Senate, Aylesworth said he’s skeptical as to whether it can advance in the House.

“I would welcome that bill to come over, but I can tell you where it’s going to go,” Aylesworth said. “Knowing the way the legislature works, if that bill got assigned to my committee, as an agricultural bill, then we’ll get to hear it. But it isn’t going to happen that way.”

    1. “everybody’s cool with it.” SMH

      Aylesworth is probably one of those elected officials that drives 90 on the interstate, knowing they won’t get pulled over with the special license plate they get.

    2. Also…”bifurcated” really only appears in the Bible. So, can tell these two R hillbillies are typical bible-thumpin’ hayseeds. Ugh. Rural Indiana. God help us.

  1. The problem is not trucks going too slow. I travel the interstates frequently and my observation is that most of them exceed the limit regularly, just as autos do. The problem in my opinion is that there are many drivers (both semis and autos) who get in the left lane and go at or below the speed limit which frequently backs up traffic unnecessarily and causes unsafe conditions. The left lane should be used for passing. Several states have posted this and changed laws that require drivers to stay right unless passing, and allow police to issue tickets to drivers who do not follow this practice and block the flow the flow of traffic. Common sense is not so common.

  2. The most aggravating situation is a semi “passing” another semi for a mile or more, in the left lane, and backing up passenger cars. I’d like to see law that prohibits semi’s from every passing another semi. Think of the fuel savings…

  3. Our two lane 65 was built for a different era. The trucks in the passing lane coupled with only two lanes creates significant public safety issues. The stretch from Lebanon to Chicago is a hot mess. Having a third lane eases the congestion. Drive on 65 in Kentucky and experience 3 lanes almost border to border. Why is Indiana is left behind on its share of federal HW dollars? What has our congressional delegation to assist (if anything)? Let’s focus on long neglected state infrastructure needs.

    1. The state has plans to make I-65 between the Indiana Toll Road and the Kentucky state line three lanes in each direction, and to make I-70 between the Illinois and Ohio states lines three lanes in each direction as well using funds from Biden’s infrastructure bill that passed Congress in 2021. By the way, all seven of Indiana’s Republican House members voted against the bill, as did your two Senators, Young and Braun (who wants to be your next governor).
