Navigating the wide, sweeping plains of Riverton and taking on the unpredictable winter stretches of US Route 26 or Highway 789 demands a vehicle equipped to handle sudden, severe road changes. Around the Wind River Valley, freezing temperatures and heavy snow frequently force migrating mule deer and big game down into lower elevations, where they congregate on plowed, snow-free roadways to travel. This drastically increases your risk of a vehicle-wildlife collision, especially during low-visibility dawn and dusk hours. That is exactly why our line of vehicles comes standard with protective safety suites like Toyota Safety Sense. The Pre-Collision System with Pedestrian Detection acts as an extra set of eyes, scanning the dark road ahead to detect sudden hazards or animals crossing your path, providing audible alerts and automatic emergency braking if you cannot react in time. To give you a clear view of the shoulders where wildlife hides, standard Automatic High Beams optimize your night vision by automatically toggling your high beams based on surrounding traffic. Furthermore, when slick river-valley ice or howling winds try to push your vehicle offline, Lane Departure Alert with Steering Assist and Proactive Driving Assist deliver gentle, proactive steering inputs and smart braking to help keep your vehicle centered, balanced, and stable on hazardous roads. Our team witnesses how these features protect local drivers every single day, making sure you stay firmly in control through the worst of our Wyoming winters.
