Is it necessary to wear a bike helmet when commuting to work?

In addition, I only ever ride my bicycle on the pavement/side walk shared by pedestrians; the only time I go on the road is when cross the lights for pedestrians.

Is it really necessary for commuters to wear a bike helmet. I just find it unnecessary to wear helmets on the street because the chances of collision and injury are a lot less than on the road, and I question the compulsory bike helmet laws.

If wearing helmets is mandatory, why don't we make the inclusion of airbags mandatory for all cars as well then?



Answer
Even when I ride on the sidewalk, which is illegal where I live, I have close calls when people are backing out of driveways and such. Not to mention the people that are getting out of their house I almost hit.

"The Crosswalk Slam

You're riding on the sidewalk and cross the street at a crosswalk, and a car makes a right turn, right into you. Cars aren't expecting bikes in the crosswalk, so you have to be very careful to avoid this one. This collision is so common we've lost track of the number of people who've told us they were hit this way, such as Ray John Ray. One study showed that sidewalk-riding was twice as dangerous as road riding, and another study said it's even more dangerous than that.

How to avoid this collision:

1. Get a headlight. If you're riding at night, you should absolutely use a front headlight. It's required by law, anyway.

2. Slow down. Slow down enough that you're able to completely stop if necessary.

3. Don't ride on the sidewalk in the first place. Crossing between sidewalks can be a fairly dangerous maneuver. If you do it on the left-hand side of the street, you risk getting slammed as per the diagram. If you do it on the right-hand side of the street, you risk getting slammed by a car behind you that's turning right. You also risk getting hit by cars pulling out of parking lots or driveways. These kinds of accidents are hard to avoid, which is a compelling reason to not ride on the sidewalk in the first place.

And another reason not to ride on the sidewalk is that you're threatening to pedestrians. Your bike is as threatening to a pedestrian as a car is threatening to you. Finally, riding on the sidewalk is illegal in some places. (In Austin, those places are the Drag, and downtown on 6th St. and on Congress). If you do plan on riding on sidewalks, do it slowly and EXTRA carefully, ESPECIALLY when crossing the street between two sidewalks."

"1. Don't ride on the sidewalk. When you come off the sidewalk to cross the street you're invisible to motorists. You're just begging to be hit if you do this. Keith Vick was killed this way in Austin, TX in Dec. 2002."

"Contrary to popular belief, you increase your chances of getting hit by car when riding your bike on the sidewalk. I know you may find it hard to believe but its true.

While riding in the street is more intimidating, it places you in a position that makes you more visible to the motorist. Usually people will ride on the sidewalk because they want to stay away from cars or they ride against traffic in the street because they are afraid of being hit from behind: they "want to see the cars coming at me". Crashes on sidewalks comprise close to fifty percent of all crash types. They are more common because every driveway forms an intersection and, if you went to driving school you may remember, that most crashes happen at intersections. In traffic engineering jargon where two vehicles cross paths is referred to as a conflict point and traffic engineers work very hard at reducing or eliminating conflict points.

Essentially every driveway that crosses the sidewalk forms a conflict point. Couple this with motorists not stopping at the sidewalk before entering the street and looking at traffic in the street not for bicyclists on the sidewalk and you have recipe for a crash. By cycling in the street you completely avoid these conflict points. The motorist stops before entering the street and is looking where you will be before they cross your path. While these crashes are usually not fatal, they can easily result in an incapacitating injury especially if you are not wearing a helmet. In my expert witness practice, the majority of sidewalk related crashes I've been involved with the rider was not wearing a helmet and usually result in brain injury"- http://ezinearticles.com/?Bicycle-Safety---The-Problems-With-Sidewalk-Riding-and-Against-the-Flow-of-Traffic&id=1857311

What club should I start next year at my school?




Kathy


So I was thinking
Future Doctors of America
or an
AP Study Group - Somewhere we can get together and study/prepare/do homework together for AP classes.

What would look better on college applications?
THANKS!



Answer
The two clubs that you'd mentioned sound like good ideas. Regarding the AP Study Group, however, I would ask the guidance counselor or Activities Coordinator if that would actually be considered a student activity club or rather a "study group", know what I mean. The Future Doctors of America is apparently a career interest group, just fyi :)

I'm thinking that colleges look for well-rounded students who have participated in a variety of types of clubs such as an academic and/or or language club, social group and community service types of groups.

How about considering starting a club for volunteerism, Students Against Destructive Decisions (SADD), world language club, science or math club, art club, cultural group, debate team, animal rights group, student government (if that's not already "on the docket"), environmental club, peer tutors (though meeting in neutral places such as the school itself), choir or such.

Topics that you may cover and educate your classmates and school mates about include the dangers of 'huffing' (fumes or chemical vapors), risks of 'the choking game', driving while intoxicated (DWI) and that includes any types of substances including inhalants, distracted driving (and you can make a new acronym DWI or "driving while inattentive" which includes texting, cell phone use, tuning in a radio station, engaging in conversation), the importance of wearing a helmet while riding a bicycle or motorcycle, skateboarding, skiing, riding a scooter and any other topics that may help to prevent injury to an
