10 RV Violations That Could Cost You Real Money (and Real Consequences)
Updated: Oct 7
Here's an uncomfortable truth: most RVers are breaking at least one law right now without even knowing it. Not because they're reckless — because RV rules are a confusing, state-by-state patchwork that nobody hands you when you buy the rig. And some of these "oops, I didn't know" violations carry fines that'll make your eyes water, or worse.
So let's fix that. I'm Joe — Squatch to most folks — and I'm counting down the 10 RV violations most likely to bite you, from "annoying ticket" all the way up to "could cost you everything." Fair warning: they get worse as we go. Number 10 is the one that keeps me up at night. Let's start easy and work our way up.
(Quick honesty note: I'm an RV guy, not a lawyer, and these laws vary a lot from state to state — even county to county. Treat this as your heads-up to check the rules everywhere you travel, not as legal advice.)
The 10 RV Violations, Counting Up (Least to Worst)
1. Busted or Disconnected Trailer Lights
We'll start gentle. Those trailer running lights, brake lights, and turn signals aren't optional — they're the law, and they're the first thing a bored trooper notices. A blown bulb or a corroded connector you didn't catch on your walk-around is an easy ticket and an even easier accident. The cost: a fix-it ticket and a citation — cheap compared to what's coming, but 100% avoidable if you check your lights before every trip. (This is exactly why I preach the [RV pre-trip checklist].)
2. Skipping Safety Chains, Breakaway Cables, or Trailer Brakes
Here's where "minor" starts turning into "dangerous." Most states require safety chains (crossed, and attached to the frame — not the hitch), a breakaway cable that slams on the trailer brakes if it ever separates, and working trailer brakes on anything over a certain weight (often 3,000 lbs). Skip these and you're looking at a ticket — but the real cost is a runaway trailer if something lets go. The cost: citation now, catastrophe later. Get your setup right with my [RV hitches] guide.
3. No Proper Towing Mirrors
If you can't see down both sides of your trailer, most states say you're not legal to tow. Those little factory mirrors don't cut it behind a wide rig — you need extended towing mirrors. The cost: a ticket, plus you're driving half-blind, which is how lane changes turn into insurance claims.
4. Ignoring the Lower Towing Speed Limit
This one nails people who have no idea it exists: several states set a lower speed limit for vehicles towing a trailer than for regular traffic. You'll see it on those "day/night" signs too, where the limit drops after dark. Cruising at the "normal" limit when you're towing can still earn you a ticket. The cost: a speeding citation you didn't even know you'd earned — and higher speeds are a top cause of blowouts and sway (see [RV tire blowout] and [trailer sway]).
Still with me? Good, because here's where the dollar signs start climbing.
5. Driving a Heavy Rig Without the Right License
Bet you didn't see this one coming. Some states require a special (non-commercial) license to drive or tow a heavy rig — California, Texas, and New York among them, usually kicking in over certain weight thresholds. Folks tow big fifth wheels and drive big motorhomes on a regular license for years, totally unaware. Then one inspection changes everything. The cost: fines commonly running $200 to $1,000+, and in some cases a suspended license. Ouch.
6. Letting Passengers Ride (or Sleep) in a Moving Trailer
I know, I know — it seems so convenient to have someone back in the travel trailer on a long haul. But in many states it's flat-out illegal to ride in a towed travel trailer while it's moving (some states allow it in fifth wheels with precautions — but you'd better know your states). And it's genuinely dangerous: no seatbelts, no crash protection, and studies show higher fatality rates in towed rigs. The cost: fines around $100–$250, steeper if anyone's hurt — and a risk that's not worth taking at any price. Everybody rides up front. Period.
7. Running Propane Where It's Banned
Lots of us tow with the propane on to keep the fridge cold — usually fine. But propane is prohibited in certain tunnels, on some bridges, and on many ferries (Boston's tunnels, the Baltimore Harbor tunnels, and plenty more). The signs tell you to shut the tank off before you enter, and they mean it. The cost: fines, or getting turned away and re-routed — and in a tunnel, the safety reason behind the rule is deadly serious. When in doubt, shut it off. (Brush up on propane safety in my [RV propane leak] guide.)
8. Parking Overnight Where You're Not Allowed
That "I'll just pull over and grab some sleep" instinct gets expensive. Overnight RV parking is restricted or banned in tons of cities, rest areas, and lots — and pulling onto what looks like empty land is often trespassing on private property. Block a sidewalk, bike lane, or hydrant and it's worse. The cost: parking fines commonly $50–$200, and if they tow your rig, $500+ to get it back — plus a possible trespassing charge. Always confirm overnight parking is actually allowed before you shut your eyes.
Okay. Deep breath. The last two are the wallet-killers.
9. Dumping Your Tanks Illegally
This is a big one, and people do it more than they'd admit — draining gray or black tanks onto the ground, into a storm drain, or anywhere that isn't an approved dump station. It is never legal to release your tanks onto soil or into waterways. States treat this as an environmental offense, and they do not mess around. The cost: hefty fines that climb with the volume, misdemeanor charges in states like California, cleanup restitution, community service — and in serious cases, they can even seize the vehicle used to do it. There's no version of this that's worth it. Always use a proper dump station. (New to tanks? My [RV holding tanks] guide has you covered.)
10. Towing Overweight — The One That Can Cost You Everything
Here it is — the violation that can bankrupt you, and the one hardly anyone checks. Every rig has weight ratings (GVWR, axle ratings, tow and payload limits), and blowing past them isn't just a ticket — it's a financial time bomb. Fines for running overweight reach $10,000+ in some states, and they can impound your rig until you offload. But that's not even the scary part.
Here's the scary part: if you're overweight and you cause an accident, your insurance company can deny the claim — leaving you personally on the hook for the other vehicle, the injuries, the lawsuits, all of it. That's not a ticket. That's your house, your savings, your future. An overweight rig also stops longer, handles worse, and blows tires — the exact stuff that causes the wreck in the first place.
The cost: potentially everything. And the fix is almost insultingly simple — know your numbers, weigh your loaded rig once at a truck scale, and stay under your ratings. I walk through all of it in my [RV weight ratings] guide. If you read one thing on this whole list, make it that one.
Dishonorable Mentions
A few more that'll ding you depending on where you roam:
Transporting firewood across state or quarantine lines — spreads tree-killing pests, and it's fined. Buy it where you burn it.
Campfires during a burn ban — big fines, and if your fire spreads, you're looking at criminal charges and civil liability that can ruin you. (Fire's no joke — see [RV fire].)
Restricted roads and low bridges — some parkways flat-out ban trailers, and "getting stuck" under a low overpass means damage plus a violation.
Loose pets in the vehicle — a few states actually ticket for unrestrained animals.
Squatch Tips: How to Stay on the Right Side of the Law
Know your weight, for real. It's the #1 costliest one and the easiest to fix. Weigh your loaded rig once and stay under your ratings. Full stop.
Do a real pre-trip walk-around. Lights, chains, breakaway, mirrors, tires. Ninety seconds kills half this list.
Check the rules for every state you'll cross. Speed limits, license requirements, propane tunnels, riding laws — they change at the border. A quick look before a big trip saves a world of hurt.
Never improvise a dump or an overnight spot. Use approved dump stations and confirmed overnight parking. The "just this once" is what gets people fined.
When in doubt, ask. Campground hosts, ranger stations, and yes, your friendly RV salesperson (hi) can point you right.
That's the heart of Camping with Squatch — keeping your trips fun, safe, and free of the expensive surprises nobody warned you about.
