US car seat laws by state for visitors & road trips: Mandatory rear-facing under-2 states & taxi rules (2026)

Q: 1. Which US states legally require rear-facing until age 2?

The American Academy of Pediatrics (AAP) and NHTSA advise keeping all babies and toddlers in a rear-facing car seat for as long as possible , until they reach the highest weight or height allowed by their car seat's manufacturer (which is 40 to 50 lbs on most US convertible car seats — meaning many children stay rear-facing until age 3 or 4). In addition to that medical guidance, more than 20 US states + DC now make rear-facing until at least age 2 mandatory by law , including:

Q: Do you need a car seat in an Uber or Lyft in the US?

In almost every US state (including California, Florida, Texas, Colorado, and Illinois ), yes — Uber and Lyft vehicles are subject to state child passenger safety laws, and drivers will refuse a ride if you do not have a car seat for your baby or toddler. New York City is the main exception where TLC-licensed rideshares and yellow taxis are legally exempt, though using an Uber Car Seat or bringing a lightweight travel car seat is always safer.

Q: At what age can a baby face forward in a car seat in the US?

In more than 20 US states (including California, New York, Hawaii, Colorado, Illinois, Pennsylvania, New Jersey, Virginia, and Washington), state law makes it mandatory to keep children rear-facing until at least age 2 (unless they exceed 40 lbs / 40 in). Furthermore, the AAP and NHTSA recommend keeping toddlers rear-facing until they hit the maximum rear-facing weight or height limit of their convertible car seat (typically 40–50 lbs).

Key facts

Short answer: more than 20 US states + DC (including California, New York, Hawaii, Colorado, Illinois, PA, NJ, VA, and WA) legally require children under 2 years old to ride rear-facing. Taxis and TLC Uber/Lyft cars are legally exempt in New York City, but rideshares are NOT exempt in California, Florida, or Texas.

Unlike the United Kingdom or European Union — where a single national car seat regulation (UN ECE R129 / R44) applies across the country — child car seat laws in the United States are set state by state, while car seat manufacturing standards (FMVSS 213) are set federally by NHTSA.

That means driving across a state line (or landing at a new airport and calling an Uber) can change two rules immediately:

Whether rear-facing is legally mandatory until age 2: More than 20 US states plus Washington, DC now make it illegal to turn a child forward-facing before their 2nd birthday (unless they exceed specific 40 lb / 40 in thresholds).
Whether taxis and Uber/Lyft rideshares are exempt from car seat laws: In New York City, yellow taxis and licensed TLC Uber/Lyft cars are legally exempt from child restraint laws. In California and Florida, taxis and rideshares are NOT exempt — meaning you cannot legally ride in an Uber from LAX, SFO, or Orlando (MCO) without a car seat!

Here is the complete, sourced guide to US baby and toddler car seat laws across top family travel states (checked October 2026).

1. Which US states legally require rear-facing until age 2?

The American Academy of Pediatrics (AAP) and NHTSA advise keeping all babies and toddlers in a rear-facing car seat for as long as possible, until they reach the highest weight or height allowed by their car seat's manufacturer (which is 40 to 50 lbs on most US convertible car seats — meaning many children stay rear-facing until age 3 or 4).

In addition to that medical guidance, more than 20 US states + DC now make rear-facing until at least age 2 mandatory by law, including:

West Coast & Pacific: California, Hawaii, Oregon, Washington
Northeast & Mid-Atlantic: New York, New Jersey, Pennsylvania, Connecticut, Rhode Island, Vermont, Maine, New Hampshire (effective 2025), Maryland, Virginia, Washington, DC
Midwest, Mountain & South: Colorado (updated law effective Jan 1, 2025: rear-facing under age 2 and 40 lbs!), Illinois, Michigan (updated law effective April 2025: rear-facing under age 2!), Nebraska, Oklahoma, Louisiana, South Carolina

Bottom line for road trips: If your child is under 2 years old, keeping them rear-facing guarantees you comply with the law in all 50 states!

2. Uber, Lyft & taxis with a baby in the US: how to get from the airport legally and safely

Even in the handful of cities where municipal taxicabs have a 1970s legal exemption from car seat laws, Uber and Lyft drivers drive personal vehicles and can be ticketed (or lose their insurance coverage) if they carry an unrestrained infant in states like California, Florida, or Texas. Here are the four ways to handle airport transfers and city rideshares in the US:

Bring a lightweight baseless or folding travel car seat:
Infants (0–12 mos): The Doona Car Seat & Stroller (17.2 lbs, $550) converts from your stroller into a baseless FAA-approved car seat at the curb in 2 seconds. Or carry a Joie i-Snug 2 (7.4 lbs) or CYBEX Cloud T (9.9 lbs) and install it without the base using the car's 3-point seatbelt.
Infants & Toddlers (3 mos – 3+ yrs): The Cosco Scenera NEXT weighs just 6.8 lbs (3.1 kg) and costs $59 — you can install it with a seatbelt in an Uber in 45 seconds and hang it on your stroller handlebar when you get out.
Toddlers (2+ yrs, 22–50 lbs): The WAYB Pico Folding Car Seat (8 lbs, $380) folds into a small backpack and installs forward-facing in any Uber or taxi in under a minute.
Book "Uber Car Seat" (New York City, Orlando & select cities): In New York City, Orlando, Los Angeles, and Washington, DC, Uber offers an Uber Car Seat vehicle option equipped with one Nuna Rava convertible car seat (rear- or forward-facing from 5 to 65 lbs) for an extra ~$10 surcharge.
Use Disney Minnie Vans at Walt Disney World: On Walt Disney World property in Florida, every Minnie Van (ordered through the Lyft app) comes with two Graco convertible car seats already on board, and Disney cast-member drivers are trained to install them rear- or forward-facing for you!
Take airport rail or motorcoach shuttles (No car seat required): Under federal NHTSA/FMCSA rules, trains (Amtrak, NYC LIRR/Subway, DC Metro) and commercial motorcoach buses (like Mears Connect to Disney World or National Park shuttle buses) do not require child car seats.

FAQs

Do you need a car seat in an Uber or Lyft in the US?

In almost every US state (including California, Florida, Texas, Colorado, and Illinois), yes — Uber and Lyft vehicles are subject to state child passenger safety laws, and drivers will refuse a ride if you do not have a car seat for your baby or toddler. New York City is the main exception where TLC-licensed rideshares and yellow taxis are legally exempt, though using an Uber Car Seat or bringing a lightweight travel car seat is always safer.

At what age can a baby face forward in a car seat in the US?

In more than 20 US states (including California, New York, Hawaii, Colorado, Illinois, Pennsylvania, New Jersey, Virginia, and Washington), state law makes it mandatory to keep children rear-facing until at least age 2 (unless they exceed 40 lbs / 40 in). Furthermore, the AAP and NHTSA recommend keeping toddlers rear-facing until they hit the maximum rear-facing weight or height limit of their convertible car seat (typically 40–50 lbs).

Can a baby car seat go in the front passenger seat of a rental car in the US?

Never place a rear-facing infant or convertible car seat in front of an active front passenger airbag — it is both life-threatening and illegal across US states. Several states (including California and Washington) legally require all children under 8 to 13 years old to ride in the rear seat whenever a back seat is present.
