The stretch of I-77 between Winnsboro and Columbia doesn't look the same after 6 p.m. Those wooded Piedmont hillsides that feel pleasant in daylight turn into solid walls of black, and ambient light disappears by Exit 41. Trucks running the Charlotte-to-Columbia freight route don't slow down just because your visibility does. So if you're making that evening run regularly, the drive that deserves attention is the one after dark, and the real test is whether your safety systems are calibrated for what that road becomes at night.
The short answer is yes, because Chevrolet built the 2026 Chevrolet Equinox with exactly these conditions in mind. Chevrolet lists more than 15 standard safety and driver-assistance features on the 2026 model, and several of them do their most important work after dark. What follows is what's actually happening when those systems activate on a Piedmont commute.

What's Actually Going on When the Road Gets Dark?
The I-77 corridor near Winnsboro throws three specific problems at an evening commuter that a generic highway drive doesn't, and none of them is exotic on its own, but they stack up fast after the light drops, with wooded terrain, steady truck traffic, and low-contrast merges all landing on the same road once it's dark.
| Condition | What Triggers It | Which Feature Responds |
|---|---|---|
| Ambient light drops past Exit 34 | Wooded terrain, no streetlights, rolling hills | IntelliBeam automatic high beams |
| Truck lanes shifts on a 4-lane, 70-mph corridor | Charlotte-Columbia freight traffic | Forward Collision Alert + Lane Keep Assist |
| Unlit merge zones and exits near wooded on-ramps | Low contrast at entry/exit points | Automatic Emergency Braking |
| Lane markings fade under fog in low-lying areas | Piedmont hollows collect ground fog at night | Lane Departure Warning alert |
| Deer crossing zones along wooded roadsides | Fairfield County's wooded rural character | IntelliBeam + Front Pedestrian and Bicyclist Braking |
Every one of those rows maps to a standard feature you'll find on every 2026 Equinox trim. No upgrade package required.
The System That Does the Most Work After Dark
IntelliBeam is the feature to understand first here, and it reads oncoming traffic to flip the Equinox between high and low beams on its own without the driver touching the stalk, a real help on an unlit corridor, though it only works with the light range a clean headlight lens can pass. On a stretch of I-77 with no streetlights and a rolling hillcrest every half mile, that matters more than it sounds. High beams at the wrong moment blind an oncoming driver, and manually toggling them on a tired commute home is a distraction you don't need. Chevrolet makes IntelliBeam standard on every 2026 Equinox trim, so this isn't a feature you have to shop for. It's just there.
Lane Keep Assist with Lane Departure Warning addresses a different problem entirely. The system monitors lane markings, and if the vehicle starts to drift without a turn signal active, it nudges the wheel gently back. Chevrolet's larger Traverse uses a similar system, but on a compact SUV that's already easy to place in a lane, the pairing of alert plus correction is genuinely reassuring when you're easing through a foggy Piedmont hollow at mile marker 38.
One honest tradeoff is worth flagging, because Lane Keep Assist can feel overly sensitive in construction zones where temporary lane markings overlap older paint. I-77 near Winnsboro sees periodic resurfacing work. The system is adjustable and can be turned down or off when conditions call for it, but if you don't know that setting exists, an unexpected steering nudge through an active construction zone can rattle you, especially the first time.

The Following Distance Problem Commuters Underestimate
Forward Collision Alert uses radar and cameras to track the vehicle ahead, calculate closure rate, and warn the driver before things turn critical, and it's a strong backstop, though it works best as the second layer after you've already kept a sane following distance yourself. The Following Distance Indicator goes one step further, showing you your gap from the car ahead in seconds, right there on the instrument cluster where you'll actually see it. Chevrolet includes both as standard on the 2026 Equinox.
Why does this matter on I-77 specifically? Truck traffic between Charlotte and Columbia runs moderate but steady on this corridor, and a loaded semi doing 65 in the right lane doesn't read the same in your headlights at 70 mph as it does in daylight. Reaction times get compressed. The Following Distance Indicator keeps that gap visible before Forward Collision Alert has to do any heavy lifting.
DIY Check vs. Seeing Our Service Team
A few of these checks you can genuinely handle yourself before tonight's commute, and a few you really shouldn't, so it helps to know which is which before you're squinting at a dashboard alert in the driveway at dusk. Make sure your headlights are clean, since the Piedmont's summer pollen and road grime build up fast, and a film on the lens noticeably cuts IntelliBeam's range. Check that the forward-facing camera (mounted near the rearview mirror) isn't blocked by a toll sticker or a suction-cup mount. Both are five-second checks that keep the system working the way Chevrolet intended. Do them before you pull out.
What you shouldn't try to fix yourself is a persistent Forward Collision Alert that fires with nothing ahead, or a Lane Departure Warning that triggers on a straight road with clear markings. Those patterns usually point to a sensor calibration that's off, often after a windshield replacement or a minor parking-lot impact that shifted the camera mount. Chevrolet's calibration process needs the right equipment, so this isn't a guess-and-check situation.
Our service center team handles sensor calibrations regularly. If a system that worked fine last month is behaving differently now, that's the conversation to have with us, not one to troubleshoot alone.
Frequently Asked Questions
Does the 2026 Equinox have automatic high beams as a standard feature?
Yes. IntelliBeam automatic high beams are included in the Chevy Safety Assist package, which Chevrolet makes standard on every 2026 Equinox trim at no additional cost. The system automatically switches between high and low beams based on surrounding traffic, which is particularly useful on unlit rural stretches of I-77 between Winnsboro and Columbia.
Why is my Equinox's Lane Keep Assist giving unexpected steering inputs at night?
The most common causes are faded or overlapping lane markings (common in active construction zones and on older pavement), low-contrast conditions like ground fog, or a forward-facing camera that needs cleaning or recalibration. If the behavior persists on roads with clear, fresh markings, it's worth scheduling a sensor calibration with our service center. The system is adjustable, and our team can walk you through the settings or identify whether a calibration is needed.
