A semi-truck hauling roughly 40,000 pounds of ice cream overturned on southbound Interstate 5 near Encinitas Boulevard around 5:51 a.m. Tuesday during the early morning commute. No injuries were reported, and no other vehicles were involved in the crash.
The rollover prompted the California Highway Patrol to issue a SigAlert and shut down all southbound I-5 lanes except the HOV lane near Encinitas Boulevard, according to NBC 7 San Diego. The closure came during peak morning travel hours and caused backups that stretched for miles to Poinsettia Lane, per Patch.
Cleanup Effort Follows Rollover
Cleanup operations followed the rollover, according to News Flash Insider. Specialized heavy-duty tow trucks were requested to upright the roughly 40,000-pound trailer and tractor. The recovery operation involved a 53-foot refrigerated trailer carrying frozen product, the outlet's report notes.
CHP officers directed displaced motorists onto alternate coastal arterial routes, recommending South Coast Highway, El Camino Real, and Rancho Santa Fe Road to bypass the freeway bottleneck, per the same account. The account identified those roads as alternatives to the freeway.
Another Rough Stretch for Encinitas's I-5 Corridor
Tuesday's rollover is the latest in a string of major commercial vehicle incidents on this same stretch of freeway. Twenty-nine days earlier, a FlixBus passenger bus collided with a semi-truck on southbound I-5 near the San Elijo viewpoint in Encinitas during the evening commute, sending 12 passengers to area hospitals with non-life-threatening injuries. And in December 2025, a pre-dawn big rig trailer fire near Birmingham Drive forced a 12-hour closure of two lanes and off-ramps, causing regional traffic hassles and commuter woes, according to Times of San Diego, which reported that local elected officials had questioned Caltrans and CHP response protocols after that incident.
Under California law, CHP maintains sole jurisdiction over traffic enforcement, accident investigations, and lane closures on state freeways like I-5, while local municipal police handle street-level crashes. California Vehicle Code Section 21703 bars motorists from following another vehicle more closely than is reasonable and prudent, a rule CHP frequently emphasizes during commercial truck safety investigations, with citations under the section carrying total court fees exceeding $400.
Timing Made the Disruption Worse
Regional traffic collision data compiled for San Diego County shows that peak daily crash volume typically occurs between 5 and 6 p.m. Morning commercial vehicle incidents on I-5 can also disrupt North County transit corridors after the initial crash. A morning rollover like Tuesday's can ripple across North County transit corridors for hours after the initial crash.
Encinitas has also seen ice cream turn up in unrelated local vehicle mishaps before. In October 2025, a pickup truck crashed directly into the Gelato 101 storefront on South Coast Highway 101 in downtown Encinitas, trapping and injuring a boy and forcing the truck to remain inside the shop pending a structural engineer's evaluation, according to The Coast News Group, which reported the driver was arrested on suspicion of driving under the influence. It remains unclear what caused Tuesday's semi-truck to lose control, whether driver fatigue, mechanical failure, or a cargo shift, and how long cleanup and tow operations ultimately took to clear the freeway.
