Storm alerts
A notification on this device when chain control starts, changes or lifts, or a road
closes or reopens. Pick your roads:
An alert is a heads-up that something changed, not a road report, and it can arrive a few
minutes after the change. Before you drive, check
Caltrans QuickMap or
Nevada 511 (nvroads.com), or call 511.
A few alerts a day at most; no account, no email, and you can turn them off here any time
(what we keep).
Live answer for SR-431 between Reno and Incline Village: does NDOT require chains or snow tires now, where and since when. Checked every five minutes.
Mt Rose Summit is NDOT's road end to end, and NDOT posts a chain requirement in words rather than
as a level. The line above quotes NDOT and shows the level it matches:
R-1
NDOT: "Chains or snow tires required."
R-2
NDOT: "Chains required, all vehicles except 4-wheel drive with snow tires."
R-3
NDOT's road report has no third chain level. When it gets worse than R-2, NDOT reports the road closed, and the line above says so.
On these roads Nevada goes further than its statewide rule: when a chain requirement is in place, the only vehicles allowed through without chains are four-wheel or all-wheel drive with snow tires.
Whose rules apply: The whole road is inside Nevada, Reno to Incline Village.
Carrying textile snow socks instead of chains? California counts them as chains at every level;
Nevada approves them except on its Tahoe roads. Both, with the agencies' wording:
are snow socks legal in chain controls.
Which kind to buy for your car, by clearance, fitting and wear:
cable chains, snow socks or link chains.

Check the live feed above before driving SR-431. When restrictions activate, Nevada Department of Transportation (NDOT) maintenance teams require traction devices across the highest pass on the Sierra highway network. Verify official enforcement directly with Nevada 511 or Caltrans before departure.
Current cameras and elevation points
The highway climbs rapidly out of south Reno toward Incline Village. Road crews track conditions using 8 NDOT camera locations positioned along the pass.
Mid-mountain locations capture weather moving across the ski areas and descent points:
SR-431 at Mt Rose Ski Area sits at 8,249 ft.
SR-431 at Brake Check Area sits at 8,206 ft.
SR-431 at Diamond Peak sits at 8,139 ft.
Lower elevations clear first as storms lift. Cameras track the approaches at SR-431 at Country Club Dr at 7,154 ft and SR-431 at Bullseye at 6,928 ft. Bullseye sits 1,959 ft below the summit. Check all SR-431 Mt Rose webcams to inspect surface conditions before leaving the valley.
How chain controls work on SR-431
Cold Sierra storms routinely coat the roadway above 7,154 ft while lower Reno valleys stay wet. NDOT activates highway signs at the base of both approaches when chain controls begin. Learn what the chain-control levels mean before driving into mountain checkpoints.
Placing tire chains on the roadside shoulder at 8,887 ft exposes drivers to high winds and poor visibility. Commercial trucks and passenger vehicles without snow tires face turnarounds at lower enforcement gates during active controls. Review full details on SR-431 Mt Rose road conditions for seasonal patterns.
Alternates when Mt Rose Highway closes
Deep snow, high winds, and avalanche mitigation frequently trigger temporary full closures on SR-431. When the summit gate shuts, the pass closes completely between Reno and Incline Village.
Drivers must divert to lower passes around the lake. Take I-80 through Truckee, or drive south through Carson City and climb US-50 toward Spooner Summit. Compare regional routes and check all road conditions across the Tahoe basin before choosing a bypass. Always verify live gate closures on the official Nevada 511 system.
