Does anyone know is a bike helmet could save a child's life if that child was hit by a car?




The Jolly


I know that bike helmets are essential and absolutely prevent head injuries when a child falls off a bike (assuming it fits properly and buckled, etc.)

But would a kid stand a chance if hit by a car and wearing a helmet?

In case your're wondering this question was prompted by an 8 year old being killed on his bike yesterday. He was riding with his father but he had no helmet on when a van struck him. :'(
Really? A helmet only protects the head? Well who whuda thunk it?

For chrissake, I know that. He died of a head injury. I'm asking if helmets are designed to protect in a big impact like that.

It's only dubious to a moron. I have my own child and these issues are important to me.



Answer
Sorry to hear of the accident, that's sad. I'm not good at delivering bad news, so please bear with me on this

Whilst it's tempting to say that "a helmet would have saved his life", it's not always the case. Bike helmets are made of polystyrene foam which is supposed to absorb some of the impact - essentially flattening the roundness of the head to make a bigger contact point at the point of impact, thus reducing the forces on that part of the head. As bicycling is an aerobic exercise (as opposed to motorcycling, which involves you sitting on the motorbike and not much else, at least activities-wise), a bicycle helmet needs to be ventilated or we'd overheat and pass out.

A bike helmet is supposed to be able to reduce injuries to a person falling off their bike from a height of <4 feet at a speed of <12mph. This essentially means a kid falling off his/her bike without any additional forces being exerted, as you've mentioned.

In the case of a van hitting the kid, this immediately takes the helmet out of its certification zone. This hurts to say this, but it's unlikely that the helmet would have made much difference given how they're designed to operate. One other thing to be aware of is that many helmet-certification tests allow the helmet to be taped to the test rig as well as strapped how it should be worn. This is clearly not something we'd do, and nor are we supposed to do it. When independently tested by a UK consumer magazine, many helmets failed to meet the standard (in this case EN1078, for Europe) they were supposedly certified to.

My thoughts and prayers are with his family.

What is the California state law on riding bikes with helmets?

In California, is it required by law to wear a helmet while riding within neighborhood zones only?
where can I find an online source that has more information on this?



Answer
Hey Thename,

Anyone under the age of 18 years of age has to wear a helmet while riding any bicycle, scooter, skates or skateboard on any PUBLIC roadway, highway, bicycle path or street. The key word is Public. If your neighborhood is located on a private roadway then the law does not apply on private land. Here is the California Vehicle Code section:

21212. (a) A person under 18 years of age shall not operate a bicycle, a nonmotorized scooter, or a skateboard, nor shall they wear in-line or roller skates, nor ride upon a bicycle, a nonmotorized scooter, or a skateboard as a passenger, upon a street, bikeway, as defined in Section 890.4 of the Streets and Highways Code, or any other public bicycle path or trail unless that person is wearing a properly fitted and fastened bicycle helmet that meets the standards of either the American Society for Testing and Materials (ASTM) or the United States Consumer Product Safety Commission (CPSC), or standards subsequently established by those entities. This requirement also applies to a person who rides upon a bicycle while in a restraining seat that is attached to the bicycle or in a trailer towed by the bicycle.

(b) Any helmet sold or offered for sale for use by operators and passengers of bicycles, nonmotorized scooters, skateboards, or in-line or roller skates shall be conspicuously labeled in accordance with the standard described in subdivision (a) which shall constitute the manufacturer's certification that the helmet conforms to the applicable safety standards.

(c) No person shall sell, or offer for sale, for use by an operator or passenger of a bicycle, nonmotorized scooter, skateboard, or in-line or roller skates any safety helmet which is not of a type meeting requirements established by this section.

(d) Any charge under this subdivision shall be dismissed when the person charged alleges in court, under oath, that the charge against the person is the first charge against that person under this subdivision, unless it is otherwise established in court that the charge is not the first charge against the person.

(e) Except as provided in subdivision (d), a violation of this section is an infraction punishable by a fine of not more than twenty-five dollars ($25).

The parent or legal guardian having control or custody of an unemancipated minor whose conduct violates this section shall be jointly and severally liable with the minor for the amount of the fine imposed pursuant to this subdivision.

(f) Notwithstanding Section 1463 of the Penal Code or any other provision of law, the fines collected for a violation of this section shall be allocated as follows:

(1) Seventy-two and one-half percent of the amount collected shall be deposited in a special account of the county health department, to be used for bicycle, nonmotorized scooter, skateboard, and in-line and roller skate safety education and for assisting low-income families in obtaining approved bicycle helmets for children under the age of 18 years, either on a loan or purchase basis. The county may contract for the implementation of this program, which, to the extent practicable, shall be operated in conjunction with the child passenger restraint program pursuant to Section 27360.

(2) Two and one-half percent of the amount collected shall be deposited in the county treasury to be used by the county to administer the program described in paragraph (1).

(3) If the violation occurred within a city, 25 percent of the amount collected shall be transferred to and deposited in the treasury of that city. If the violation occurred in an unincorporated area, this 25 percent shall be deposited and used pursuant to paragraph (1).

Added Ch. 1000, Stats. 1993. Effective January 1, 1994.
Amended Sec. 6, Ch. 674, Stats. 1996. Effective January 1, 1997.
Amended Sec. 1, Ch. 475, Stats. 2002. Effective January 1, 2003.
