Single-vehicle truck crash on eastbound NM-502 near Twin Tanks, one lane

A truck collision on eastbound New Mexico State Highway 502 near mile marker 8 in the Twin Tanks area prompted a Los Alamos Police response and left traffic reduced to a single lane, authorities reported. The incident occurred on March 2, 2026, and the driver was transported from the scene; injury details have not been disclosed.

Los Alamos Police responded initially to the single-vehicle crash, and LaDailyPost reported that "The Santa Fe Sheriff’s Office has taken over the scene." The available reports state only that the vehicle involved was a truck and that the driver was transported with unknown injuries; no name, age, hospital destination or classification of injury severity has been released.

Traffic eastbound on N.M. 502 at Twin Tanks was impacted by the emergency response. LaDailyPost quoted traffic advisories saying, "Traffic is down to one lane and moving slowly. Expect traffic delays." The slowdown affected motorists using East Road through the mile marker 8 corridor, a key commuter route between Los Alamos and points east.

The LaDailyPost page that carried the crash notice also posted separate local advisories unrelated to the collision. That separate advisory details crane movement following N.M. 502/East Road to Trinity Drive and Diamond Drive, arriving at 4244 Diamond Dr., with movement scheduled between noon and 1 p.m. Monday, and a closure of the east end of the Los Alamos Golf Course parking lot from noon to 5 p.m. to accommodate crane operations. Those crane logistics were posted on the same page but are not linked to the March 2 crash.

Key details remain unavailable from the public notices: no clock time for the crash, no stated cause such as road conditions or mechanical failure, no EMS agency named for the transport, and no estimated time for lane restoration or scene clearance. LaDailyPost’s account and the initial LAPD notice provide the on-scene facts listed above but do not include a formal police report number or agency statements on whether charges or further investigation steps will follow.

Officials have not provided additional updates on the driver’s condition or the sequence of events that led to the truck leaving the roadway near Twin Tanks. With the Santa Fe Sheriff’s Office reported to be handling the scene, further information on cause and clearance times will likely come from that agency or from a formal release by Los Alamos Police as their investigations continue. Drivers heading east on N.M. 502 should expect slow traffic near mile marker 8 while authorities work to clear the scene.
