Maryland Bicycle Helmet Law: Requirements, Exceptions, and E-Bikes

The Maryland bicycle helmet law requires every rider and passenger under 16 to wear an approved helmet on any highway, bikeway, or property open to the public. Riders 16 and older face no state helmet requirement. And here is the part that surprises most people: when police stop a helmetless minor, the statute directs them to issue a warning and educational materials, not a fine.¹

Who Has to Wear a Helmet and Where

Maryland Transportation Code § 21-1207.1 applies to anyone under 16 operating a bicycle or riding as a passenger. That includes a small child strapped into a rear-mounted seat and a child being pulled in a trailer. The requirement kicks in whenever the bike is on a highway, a bikeway, or any other property open to the public or used by the public for walking or driving.¹

“Property open to the public” is broader than most parents realize. A shopping-center parking lot counts. So does a shared-use path or a publicly accessible trail on private land. What the law does not reach is genuinely private ground the public does not use, such as your own driveway or backyard.

What Counts as an Approved Helmet

The helmet must meet or exceed the standards of the American National Standards Institute (ANSI), the Snell Memorial Foundation, or the American Society for Testing and Materials (ASTM).¹ All three organizations are named in the statute, though summaries online often drop ASTM.

Federal law adds a second layer. Every bicycle helmet sold in the United States must comply with the Consumer Product Safety Commission standard at 16 CFR Part 1203, which requires impact attenuation, retention system, and stability testing.² Any new helmet from a reputable retailer already meets it. Look for the CPSC certification sticker inside the shell.

How the Law Is Enforced

The statute says enforcement “shall be” by issuing a warning that explains the requirement and provides educational materials on helmet use.¹ There is no monetary penalty in the statute. An officer who stops a helmetless 14-year-old is required to hand over information, not a citation.

Some online write-ups claim the fine is $25. That figure does not appear in § 21-1207.1. Whether the warning changes behavior depends entirely on the rider and their parents.

Exceptions Written Into the Statute

The law carves out two narrow exceptions:

The helmet requirement does not apply on the Ocean City boardwalk between the inlet and 27th Street during the hours local ordinances permit bicycling there.¹
Passengers in a commercial bicycle rickshaw are exempt.¹

You may see references to a religious exemption for riders whose head coverings conflict with a helmet. The statute contains no such exemption. Individual officers may exercise discretion, but nothing in the text of § 21-1207.1 authorizes a carve-out on religious grounds.

E-Bikes and the Helmet Rule

Maryland sorts electric bicycles into three classes. Class 1 and Class 2 provide motor assistance up to 20 mph; Class 3 assists up to 28 mph.³ Because state law treats e-bikes as bicycles for road-rule purposes, the same under-16 helmet requirement applies to e-bike riders and passengers.

No Maryland law requires adult e-bike riders to wear helmets, even on Class 3 models topping out at 28 mph. Standard CPSC-certified helmets are tested against impacts typical of traditional cycling. Riders using faster e-bikes often look at helmets rated to the NTA 8776 standard, which is designed for higher impact energy.

Fitting the Helmet

A helmet perched on the back of the head does almost nothing in a crash. The National Highway Traffic Safety Administration recommends positioning the helmet level and low on the forehead, no more than one or two finger-widths above the eyebrow.⁴ The side straps should form a V just under and slightly in front of each ear. The chin strap should be snug enough that only one or two fingers fit beneath it.

A quick test: open your mouth wide. The helmet should pull down on the top of your head. If it doesn’t, tighten the chin strap. Then shake side to side and front to back. If the helmet shifts more than about an inch, adjust the straps until it stays put. Children’s helmets loosen quickly as straps get fiddled with and padding compresses, so recheck the fit often.

Why Adults Should Still Wear One

The traffic-stop consequences of skipping a helmet are minor. The civil consequences are not. Maryland is one of a small number of states that still follows contributory negligence, meaning a plaintiff found even slightly at fault for their own injuries can be barred entirely from recovering damages.⁵ Most states use comparative negligence, which only reduces recovery proportionally.

Picture a driver running a red light and hitting a cyclist who is not wearing a helmet. The driver caused the crash. But if the head injuries were worse because there was no helmet, the driver’s insurer will argue the cyclist’s own negligence contributed to the severity. In a comparative negligence state, that argument trims the payout. In Maryland, it can eliminate it.⁵

That reasoning applies to adults too, even though the statute does not require them to wear a helmet. Riding without one gives a defense attorney a straightforward argument and gives insurance adjusters a reason to push settlement offers down.

Local Ordinances Can Be Stricter

Maryland does not preempt local governments from passing tougher helmet rules. Some cities and counties impose their own requirements that reach further than the state law, so it is worth checking the local code where you ride before assuming the state’s under-16 threshold is the whole story.
