San Marcos police have identified the bicyclist killed early Monday morning in a crash on Interstate 35.
Police said Jeffery David Stevenson, 40, was hit by a semi-truck around 2 a.m. on Monday in the 5600 block of the southbound access road of I-35 in San Marcos, just south of Posey Road.
Police said the area in which Stevenson was hit was dark and unlit by street lights.
The driver told police that as he reached the top of the hill, he saw Stevenson suddenly in front of him and was unable to avoid hitting him.
According to investigators, the bicycle did not have a headlight or rear red reflector required by state law for night time operation of a bicycle.
No charges are expected to be filed against the driver of the truck.
