Mapleton resident urges action on speeding, truck braking noise on Highway 89

Mapleton — At the Mapleton City Council public forum Wednesday, Oct. 15, 2025, resident Doug Allen said drivers are speeding and some are running a red light on Highway 89 near 1800 West, and that large trucks using engine or exhaust brakes are creating a nuisance on the downhill approach.

Doug Allen, a Mapleton resident who gave his address as 1560 North 1800 West, said drivers “coming from Springville are coming up there 900 miles an hour trying to see which one's gonna get to the single lane up there by twelfth, And it's really caused a drag strip.” He added that some drivers “are not stopping for the red light,” and that he and his daughter have “come within as close as you can come to getting hit without getting hit.”

The issue drew a staff response rather than a formal council motion. A councilmember asked Rob to explain jurisdiction and options. Rob, a city staff member, said the stretch of road Allen described is under the authority of the Utah Department of Transportation and that the city will contact UDOT about requests related to engine-brake restrictions: “For the air brakes, I'll have to, check with UDOT since that is their roadway. I'll I'll, talk with them about what the what the process is about, requesting that.”

Rob also said city police and staff would discuss enforcement for speeding and red-light compliance: “...when it comes to to speeding problems on on 89, chief and I will will, can talk about enforcement and stuff.” He noted the city earlier requested UDOT assistance and that UDOT recently installed additional speed-limit signs on the corridor. Rob said the city could consider a posted lower limit — “If we changed it to 45, it might help that a little bit” — but added that past changes had not fully resolved speeding in the area.

The exchange was recorded during the public forum portion of the meeting; no formal council action, vote or ordinance addressing the Highway 89 concerns was taken at the session. Council staff committed to follow up by contacting UDOT about engine-brake signage or restrictions and coordinating with the police chief on enforcement steps.

Community members concerned about speeding or truck braking on Highway 89 can expect staff outreach to UDOT and a possible increase in local enforcement; the council did not set a timeline or announce any formal ordinance or traffic-order changes at the meeting.
