If you've ever found yourself on a long stretch of Oklahoma highway with miles of open road ahead, you already know how draining those drives can be. That's exactly why GMC's Super Cruise® is a game-changer for long Oklahoma drives — it takes the stress out of highway travel by letting your vehicle do more of the work, so you can arrive feeling refreshed instead of exhausted. What Is GMC's Super Cruise? Super Cruise® is GMC's hands-free driver assistance technology, available on several vehicles across the professional grade lineup. It uses a combination of LiDAR map data, GPS, cameras, and radar sensors to help manage steering, braking, and acceleration on compatible highways — all without requiring your hands on the wheel. It's important to note that Super Cruise® is a driver assistance feature, not a self-driving system. You still need to remain attentive and engaged while it's active. A driver attention system monitors your focus and will prompt you to take control when needed. more How Super Cruise Makes Oklahoma Highway Driving Easier Oklahoma is full of long, flat highway corridors that are perfectly suited for hands-free driving assistance. On those stretches, Super Cruise® can manage the repetitive demands of maintaining speed and staying centered in a lane, reducing fatigue over time. The system also supports automatic lane changing on compatible roads when you activate the turn signal, making it easier to pass slower traffic without the usual effort. Which GMC Vehicles Offer Super Cruise? Super Cruise® is available across a range of GMC models, including the Sierra 1500, Sierra HD, and the full-size Yukon lineup. This means no matter if you need a capable work truck or a spacious family vehicle, you can access this technology.

What You Should Know Before Using Super Cruise Super Cruise® operates on pre-mapped compatible highways across the United States and Canada. Before a trip, it's a good idea to confirm that your planned route includes compatible roads, since the system will only engage in those areas. The driver attention camera — which monitors eye focus and head position — is a key part of how the system stays safe. If you look away for too long, the system alerts you and eventually disengages if you don't respond. It's designed this way to keep you involved in the driving experience, even when the vehicle is handling the workload.
