Driveway Curb Ramps for Cars: How to Fix a Rolled Curb Without Concrete

A driveway curb ramp fills the drop between the street and a rolled curb so your tires roll up a slope instead of falling off an edge. The right one for a car is a heavy rubber ramp that sits on the curb, bolts to itself rather than to concrete, and has a drainage channel underneath so gutter water keeps flowing. Measure the width of your curb opening, confirm your curb is rolled rather than vertical, and pick a set that covers the full entry.

Why a rolled curb beats up your car

A rolled curb is the rounded, roll-over curb common in newer subdivisions and cul-de-sacs. It looks gentle, but the drop at the bottom of the driveway is still 2 to 3 inches, and every car that crosses it takes the hit twice a day. Low cars scrape their air dams and undercarriage. Lifted trucks, RVs, and loaded trailers put real weight through the drop. Over time the repeated impact works on struts, shocks, and steering components and pulls wheels out of alignment, which shows up later as uneven tire wear.

A ramp turns that drop into a slope. BRIDJIT, the manufacturer of the ramps below, reports that its ramps reduce the jolt of a rolled curb by as much as 80%.

Rolled curb or vertical curb? Check this first

This is the one thing to settle before you buy anything. Stand at the street and look at your curb's profile:

• Rolled curb: a rounded hump that cars already drive over. Rubber driveway ramps are shaped for this and sit on top of it.
• Vertical (square) curb: a flat 6 in face with a sharp top edge. Driveway ramps made for rolled curbs do not fit this profile. If your driveway has a vertical curb with a cut apron, you probably do not need a ramp at all; if there is no cut, the fix is a curb cut through the city, not a ramp.

Rolled curbs vary by neighborhood, so compare your curb to the dimension drawing on the product page before ordering. If you are not sure, text us a photo of your curb and we will tell you which set fits.

Rubber vs. metal vs. DIY curb ramps

Rubber is the standard for driveways. Molded recycled-tire rubber is heavy enough to stay put without anchors, flexes to follow a curved curb, does not rust, and is quiet under tires. It is also the material that cities and HOAs are used to seeing at the curb.

Metal ramps have their place, but not at a residential driveway. Aluminum and steel plates are loud, slide on wet concrete unless anchored, and the drilled anchors are exactly what most municipalities prohibit in the gutter.

DIY ramps, whether poured concrete, asphalt, or a stack of lumber, have one problem in common: they block the gutter. Storm water backs up at the curb, the city or HOA sends a letter, and you remove it. Poured concrete in the gutter is also illegal in many cities because it is permanent work in the public right-of-way. A removable rubber ramp with a drainage channel avoids both issues.

What makes a driveway ramp HOA- and city-friendly

Rules vary by city and association, so check yours before installing. The features that usually satisfy them:

1. Nothing anchored. The ramp bolts to itself, never to the curb. No drilling, no adhesive, no concrete.
2. A drainage channel underneath. Gutter water must pass under the ramp, not pool behind it. This is the detail most ordinances care about.
3. Tapered outside edges. The left and right ends slope away so delivery trucks and street sweepers cross without catching and there is no lip to trip over.
4. Removable. If you move or the rules change, it comes off without a trace.

Permanent set or portable pair?

A permanent set spans the full driveway opening, bolts together into one run, and stays at the curb. Choose it if you own the home and cross the curb every day. You never think about it again.

A portable pair is two loose sections you set under each tire track when you need them and pick up when you do not. Choose it if you rent, your HOA rules out anything left at the street, or you need the ramp at places you do not control: a friend's driveway, a job site, a campground. The trade-off is placement: set one section per tire track, spaced to your vehicle's width, and drive at them straight. Taken at an angle, loose sections can shift.

Driveway curb ramps compared

Both ramps are molded in the USA from 100% recycled tires, sit on rolled curbs without anchors, ship free, and carry a five-year manufacturer warranty.

The expandable set follows a curve: the bolts are left loose on purpose so the run flexes around a cul-de-sac or corner-lot entry. You can add center sections to an installed set later using the same bolts. See both in the BRIDJIT collection or browse all curb ramps.

How to size a permanent set

1. Measure the width of your curb opening at the street, from where the curb starts to roll on one side to where it stops on the other.
2. Pick the set whose coverage meets or exceeds that width. A set that stops short leaves one tire dropping off the curb; the tapered ends are meant to sit past the driveway edges, not inside them.
3. If your entry is curved, the set still works. The loose joints follow the arc.
4. Not sure between two sizes? Buy the smaller set and add a center section later if you need it.

Installation and upkeep

Two people, a hammer, a screwdriver, and about 30 minutes. Sections are labeled left, center, and right. Lay them along the curb in order, tap the pre-set 1/2 in galvanized bolts through, thread on the nuts and leave about 1/4 in of thread showing so the joints can flex, then flip the assembled run onto the curb and nudge it into place. No tools touch the concrete.

Twice a year, flip the ramp up and clear leaves and grit from the drainage channel, more often if your gutter collects debris. If you will not be moving or expanding the set, crimp the exposed bolt threads with pliers so the nuts cannot be removed without tools.

Low cars, RVs, trailers, and everything else on wheels

Anything that crosses the curb benefits: sports cars and anything with a low air dam, lifted trucks, RVs and motorhomes, boat and utility trailers, golf carts, motorcycles, hand trucks and wheeled bins. The 2.5 in crown tapers to 3/4 in at the road edge, so the approach angle is shallow enough for low-clearance cars and the run is long enough for an RV's wheelbase to settle onto it.

Frequently asked questions

Are driveway curb ramps legal?

Most cities and HOAs allow a removable rubber ramp that is not anchored to the curb and does not block the gutter. Poured concrete or asphalt in the gutter is prohibited in many cities because it is permanent work in the public right-of-way. Check your local ordinance and HOA rules before installing.

What size curb ramp do I need for my driveway?

Measure the width of your curb opening at the street and choose a set that covers it: 3-piece for 11.75 ft, 4-piece for 15.7 ft, 5-piece for 19.6 ft, 6-piece for 23.5 ft. If in doubt, buy smaller and add a center section later.

Will a curb ramp block water in the gutter?

Not if it has a drainage channel. BRIDJIT ramps have a 2.5 in channel running the full length of the underside so storm water passes under the ramp. Solid DIY ramps without a channel are what cause gutter backups.

Do curb ramps work on a curved driveway entry?

Yes. The expandable set's bolts are left loose by design so the joints flex to follow a cul-de-sac or corner-lot curb.

Can I use a driveway curb ramp with an RV or trailer?

Yes. The ramps are made for anything on wheels that crosses a rolled curb, including RVs, motorhomes, and boat and utility trailers. Choose a set wide enough to cover the full entry so both sides of the vehicle cross at once.

Will a curb ramp fit a vertical curb?

No. These ramps are shaped for rolled curbs only. If your curb is a flat 6 in face, contact us before ordering.
