Fall Riding in California
Why Late Summer and Early Fall Are Especially Hazardous — and What to Do About It
California’s fall months might be the most beautiful time of year to ride. The sun dips lower in the sky, the coastal fog rolls back, and the air finally cools enough to make long rides comfortable again. The state’s most scenic routes—Highway 1, Highway 9 through the Santa Cruz Mountains, and the backroads of the Central Coast—are full of color and crisp air that feels tailor-made for motorcycles.
But here’s the truth that most riders learn the hard way: late summer and early fall are also among the most dangerous times to ride in California.
Every year, as the seasons shift, we see a spike in serious motorcycle accidents across the state—from early morning crashes caused by glare or dew, to multi-vehicle pileups on rural roads where fallen leaves or oil buildup make traction unpredictable.
In late August, an early-morning crash on eastbound I-80 in Davis made headlines after a motorcycle went down and caused lane closures for hours (CBS News Sacramento, October 2025). It’s a stark reminder that as conditions change, so do the risks.
At McCarthy Motorcycle Law—California’s Motorcycle Law Firm, built by riders, for riders—we’ve handled enough fall crash cases to know this pattern is real. The good news is: most of these crashes are preventable with awareness, preparation, and the right mindset.
Let’s talk about what makes this time of year so hazardous—and what you can do to ride smart, stay safe, and protect your rights if the unexpected happens.
Why Fall Riding Is Especially Dangerous in California
1. Shorter Days and Sudden Darkness
In summer, you can head out after work and still have hours of daylight left. By October and November, that luxury is gone. Twilight sneaks up faster than you think—especially if you’re riding through canyons, redwood forests, or coastal fog.
Reduced visibility is one of the top contributing factors in motorcycle accidents this time of year. Drivers aren’t expecting to see motorcycles in the dim light, and riders who misjudge sunset timing often find themselves navigating back roads in near-dark conditions.
Pro tip: Always check sunset times before you head out. Bring a clear visor, keep your headlight lens clean, and use reflective elements on your jacket or panniers. It’s not about fashion—it’s about being seen.
2. Glare and the “Golden Hour” Problem
Fall sun sits lower on the horizon, especially during morning and evening commutes. That “golden hour” light might make for beautiful photos—but it’s brutal for visibility.
A blinding burst of sunlight can render both you and other drivers momentarily blind, especially on west- or east-facing highways like 101 through Santa Barbara, I-5 through Stockton, and 80 through the East Bay and Sacramento. Glare can also mask brake lights or turn signals until it’s too late.
Pro tip:
Use a drop-down internal visor or lightly tinted shield. Avoid riding directly into or away from the sun during peak glare hours if you can. And always keep your visor clean—dust and bug film can amplify glare.
3. Leaves, Branches, and “Invisible” Hazards
In northern and coastal California, fall means debris—lots of it. Leaves, small branches, and eucalyptus bark litter the roads after every gust of wind. On shady backroads or beneath redwoods, those leaves stay damp and slick.
A patch of wet leaves can be as slippery as oil. Combine that with sand or gravel from recent grading, and you’ve got a recipe for disaster—especially mid-corner when traction is already limited.
Pro tip:
Take corners slower than usual, especially after a storm or wind event. Watch for shiny patches on pavement that might be oil or moisture. Remember that visibility isn’t just about what you can see—it’s about what’s hiding under that next pile of leaves.
4. Tourists, Harvest Traffic, and Distracted Drivers
Fall isn’t just riding season—it’s travel season. Wineries are in full swing, harvest festivals are everywhere, and tourists flood coastal and mountain roads. Unfortunately, that means more rental cars, RVs, and distracted drivers focused on GPS instead of mirrors.
Central Coast riders know this well: stretches like Carmel Valley Road, Foxen Canyon, and Santa Rosa Creek can transform from quiet backroads to traffic jams of out-of-towners in seconds. For riders, that means unpredictable slow-downs, unsafe passing, and vehicles turning into driveways without signaling.
Pro tip:
Increase following distance and scan far ahead for signs of brake lights or dust plumes. Expect cars to wander over the centerline on twisty scenic roads—and position yourself defensively.
5. Abrupt Weather Shifts
You can leave Monterey in sunshine and hit dense fog by Big Sur. Climb from the coast to 101 near Paso Robles, and it might jump 25 degrees in minutes. The Sierra passes? They can drop from 70°F to 40°F by the time you crest.
Rapid weather changes affect not just comfort—but control. Cold tires lose grip, fog reduces reaction time, and rain brings out every drop of oil embedded in the asphalt from the summer.
Pro tip:
Always check multiple weather zones for your route, not just your destination. If you’re headed into elevation or toward the coast, pack layers and waterproofs. And when the first rain hits after a long dry spell—give the roads at least 24 hours to wash clean before you ride hard.
Preparing Your Bike for Fall Riding
Your bike might have handled the summer perfectly—but fall conditions test every system differently. A quick pre-ride check can make all the difference.
Tires
Tire pressure fluctuates with temperature. As air cools, you lose PSI—and that can mean slower response, less grip, and faster wear. Cold roads also demand more tread depth to evacuate moisture.
Check pressure before every ride (not just “every once in a while”).
Replace worn tires before they become a liability—especially the front.
If your tires are over three years old, inspect for cracking or hardening.
Lighting
You’ll be riding in dimmer light, so your visibility equipment matters.
Clean your headlight lens and check alignment.
Upgrade to LED if you haven’t already.
Check brake light operation—many riders discover theirs isn’t bright enough until it’s too late.
Battery
Cold mornings can expose weak batteries. A slow crank in the driveway is one thing; being stranded at a turnout on Highway 9 is another.
Keep a small lithium jump pack in your bag.
Consider a tender if your bike will sit between rides.
Brakes and Fluids
Oil thickens and brakes can get spongy in cooler weather. If you’re due for a flush or oil change, do it now before winter storage.
Gear Up: Riding Smart for the Season
Visibility Is Everything
Even experienced riders underestimate how “invisible” they become as days shorten. Add high-viz strips to your jacket, tail bag, or helmet. A little reflective piping can catch a driver’s eye at the right time.
Layer Like a Pro
California’s microclimates demand flexibility. A moisture-wicking base, an insulating mid-layer, and a windproof shell will let you adapt to changing temps without over-packing.
Fog and Face Shields
Consider a Pinlock insert or anti-fog spray. In mountain or coastal rides, fog can turn your visor into a mirror. Carry a microfiber cloth in an easy pocket for mid-ride cleanups.
Riding Technique Tips for Fall Conditions
Ride Smooth — Gentle throttle, smooth braking, no abrupt mid-corner corrections. Cold tires and slick debris punish jerky inputs.
Use Both Lanes of Vision — Scan beyond your immediate path. Look for patches of shade, puddles, or leaf buildup.
Brake Earlier — Give yourself extra distance; cooler air and damp surfaces increase stopping time.
Watch the Shoulders — Edge buildup of gravel and leaves is common near ditches or vineyard drives.
Mind the Fog Line — When visibility drops, staying too close to the fog line puts you near the soft shoulder where debris accumulates.
The Legal Side: What to Do If a Fall Ride Goes Wrong
Even with preparation, accidents happen—and this season brings its own legal complications.
1. Fewer Witnesses, Less Traffic
Fall rides often happen early in the morning or late in the afternoon when traffic is light. That means fewer witnesses if a crash occurs. If you go down in a low-traffic area, it could be minutes—or longer—before help arrives.
What to do:
If you can, use your phone to take photos immediately—vehicle positions, road debris, skid marks, and surroundings. Note weather, light conditions, and time of day. These details become critical in proving negligence later.
2. Police Reports May Miss Key Details
Law enforcement tends to assume “the motorcycle lost control.” But weather, glare, or debris can be contributing factors—and those details often get left out of initial reports.
What to do:
Contact a law firm familiar with motorcycle cases as soon as possible. A good motorcycle lawyer will send an investigator to document the scene properly before the evidence disappears with the next wind or rain.
3. Insurance Adjusters Blame the Rider
When conditions are variable, insurers love to argue “you should have slowed down.” That may not reflect reality. They weren’t there—and they often don’t understand what a responsible rider actually does in shifting conditions.
What to do:
Don’t give recorded statements or accept partial blame until you’ve spoken to an attorney. At McCarthy Motorcycle Law, we’ve seen countless riders blamed unfairly for crashes caused by poor road maintenance or distracted drivers. We fight those narratives head-on—with the facts and the physics.
