JACKSON, Wyo. (AP) — Motorists are being asked to show a little more care after a vehicle struck and killed a moose on state Highway 390 near Jackson.

The Associated Press says the adult cow was hit northwest of town Thursday night on a section of highway known for being particularly deadly for moose. It was the third fatal vehicle-moose collision reported in the area this winter.

After nine moose were killed in the winter of 2010-11 and another six were killed last winter, nighttime speed limits were reduced, roadside vegetation was cleared and radar signs were installed.

Leigh Work, executive director of the Jackson Hole Wildlife Foundation, says it's too early to say if the measures are responsible for the decrease in collisions.
