Tampa, FL (July 20, 2026) – Two drivers were arrested on suspicion of impaired driving following a string of early-morning collisions and a chase in Tampa, according to the Florida Highway Patrol. Troopers were first called to a three-vehicle wreck on I-4 around 3 a.m. on Saturday, July 18.
While speaking with 22-year-old Julian Arriaga Mendoza, one of the drivers, troopers noted signs of impairment, including bloodshot eyes and slurred speech. Mendoza reportedly said he hadn’t seen the other vehicles before striking them. He completed sobriety exercises but declined a breath test and was arrested on charges of DUI with property damage and refusal to submit to testing. All but one lane of westbound I-4 was shut down as crews cleared the roadway.
While troopers were still on site, a Mercedes SUV passed by with its occupants shouting at the people involved, then struck the back of a tow truck working to remove vehicles. The driver, 40-year-old Demario Carlos Morales, fled after troopers told him to stop, prompting a chase that ended at Pierce Street and East Henderson Avenue. Troopers said Morales showed similar signs of impairment and also refused testing. He now faces DUI, property damage, and hit-and-run charges.
Legal proceedings against both men are expected to move forward in the weeks ahead.
How Do Officers Determine Impairment During a Traffic Stop?
When a driver is suspected of impairment, officers typically look for a set of physical and behavioral cues. Slurred speech, bloodshot eyes, and unsteady movements are common signs that prompt closer evaluation. The smell of alcohol on someone’s breath is noted as well, though it’s only one piece of a larger picture.
Field sobriety exercises are a standard next step. These tests ask a driver to complete simple physical tasks, such as walking in a straight line or standing on one leg, to check balance and coordination. Officers use the results, along with their initial observations, to decide whether further testing is warranted.
A breath test is usually the final step, measuring blood alcohol content directly. Drivers can decline this test, but doing so carries separate legal consequences depending on the state. Refusal doesn’t end a case: it simply becomes another factor considered when charges are filed.
