Ninh explains, The Rules of Roller Derby The object of the game is to score more points

than the opposing team.

Roller derby is a sport played on skates either on a flat track, or on a banked track where

the track is raised and angled.

A roller derby team consists of 14 players, with 5 players taking to the track at any

one time.

Look closely, and you'll notice a group of each teams players pushed together.

Both teams will field four blockers, and this is collectively known as the pack.

Teams cannot be more than 10ft apart in this pack.

The key person to look out for is the jammer.

These are the players with the stars on their helmets that start behind the pack.

When the whistle blows, the clock starts for a period of two minutes.

This is known as a jam.

The goal of the jammer is to race the opposing team's jammer to try and force their way

through the pack of players.

Once a jammer has beaten the other jammer, they become the 'lead jammer', and they

race around the track.

Each jammer gets one point for every opposing player that they lap or skate past.

Once two minutes have expired, the whistle blows and that is the end of the jam.

However, a jam can also be ended early by the lead jammer, by tapping her hips like

this.

It pays to be the lead jammer as you effectively have control of the clock.

The whole process starts all over again, and the main strategy behind this game is for

a lead jammer to score as many points as possible, and to stop the clock before the other jammer

scores too many points.

The job of the blockers is to prevent the other jammer from getting past, whilst at

the same time trying to help their own jammer pass opposing players.

They are both the offence and the defence.

They are allowed to form walls with teammates, slow the opposing player down and use their

hips and shoulders to lever their opponents out of the way.

The game is played in two 30 minute halves for a combined playing time of 60 minutes.

Highest score at the end of time, wins.

That's the basics of Roller Derby, but there's a few other things you'll need to know before

playing or watching a game.

For example: Pivot

One of the blockers on each team will be wearing a stripe on their helmets.

These are the pivots.

As well as being a blocker, they dictate the pace of the pack and they direct team strategy.

They also have the special ability to become the jammer in the middle of the jam.

This is done by taking the star from the jammer.

Out of bounds.

You cannot skate out of the area of the track, accidentally or otherwise.

If you do, you must re-enter the track behind the opposing teams pivot.

Contact.

Contrary to popular belief, you cannot punch, trip, kick, elbow, clothesline, hit or slam

your opponent into the floor.

Officially, players are allowed to make frontal and side body contact above the knees, but

sometimes players don't comply.

Players who make illegal contact are given penalties.

Penalty If found guilty of breaking the rules, the

referee may award a 30 second penalty against a player.

The offending player must sit in a penalty box for 30 seconds whilst a jam is in play.

If a skater accrues 7 penalties, they are immediately disqualified from the game.

Power Jam If a jammer is hit with a 30 second penalty,

the opposing jammer has 30 seconds to score as many points as she can, knowing that the

other team cannot score.

This is known as a power jam and can be a real advantage to a team.

How to Get the Cheapest Car Insurance for Teens - Duration: 6:12.

How to Get the Cheapest Car Insurance for Teens

Car insurance is an expensive component of car ownership. Throw in a teen driver and your rates could sky rocket.

Keep your cool when purchasing insurance for your teen. Learn what discounts are available, what car to buy, and what coverage to choose to keep your rates as low as possible. Good Student Discount for Teen Drivers.

Start with the discount specifically created for teens. Insurance companies have determined good students are better drivers. Most insurance companies offer a good student discount that can really boost your savings. Encourage good grades averaging above a 30 grade point average.

Have your teen's most recent report card ready to go when purchasing car insurance. If a 30 isn't possible at the time you add your teen driver, the discount can always be added on at a later date if the grade point average improves.

Is the Teen an Occasional Operator?. Sharing a car with your teen is a great way to save some cash. Most carriers can then list your teen driver as a secondary or occasional driver.

Make sure to mention it to your agent because it is possible for this discount to slip through unnoticed. Choosing the Right Vehicle for a Teen Driver.

If sharing is still not in your teen's vocabulary or busy schedules just don't allow for sharing, be smart about picking out a vehicle for your teen. Look for something reliable yet affordable.

You don't want your teen stranded on the side of the road, but at the same time you don't want to take out a loan on their vehicle either.

Depending on your price range, look for a vehicle ranging in age from 6 to 10 years old. Check for air bags and other safety features.

Liability insurance on a car with air bags is cheaper verses one without because air bags reduce the potential of serious injury. PLPD Coverage. Selecting the right coverage for your teen driver could potentially save you hundreds of dollars.

If you followed the rules above about choosing the right vehicle, you are in a good position to insure the vehicle with personal liability and property damage, PLPD, only.

To get PLPD only you cannot have a loan on the vehicle, and you'll want to be in the position where you can replace the car on your own if something were to happen to it.

PLPD is the least amount of insurance you can purchase making it the cheapest. Physical damage is the most expensive coverage for a teen driver. Avoiding physical damage coverage such as comprehensive and collision can save you a lot on car insurance premiums.

A licensed teen away at school still needs to be insured. Even when your teen won't have access to a vehicle insurance is usually still required because they will come home from time to time.

An even deeper discount is available through most insurance carriers for students away at school. If your teen is away at school make sure your insurance company knows about it. Insure on Parent's Policy or on a Separate Policy.

Which is cheaper adding a teen onto their parent's policy or on a separate policy?. It is a tricky question to answer. Insurance companies vary so much it's impossible to say which the best route to go is.

Theoretically, adding a young driver to their parent's policy would be the cheapest way to go. The teen driver would get all the parent's big discounts such as multi-car and multi-policy.

Some insurance companies have to rate a teen on all the vehicles on the policy, not just the one being driven by the teen.

This is the biggest reason it may be cheaper to put a teen on a separate car insurance policy.

If a teen is automatically rated on all the vehicles and a couple of the vehicles have full coverage, you will be paying a higher rate.

Having a teen on a separate policy ensures the insurance company is only charging for the use of one vehicle. Major discounts can sometimes extend to a teen on their own policy if they live in the same household as another policy holder with the same carrier.

Teen drivers can be very expensive to insure. Think ahead when it comes to insuring your teen.

Start working harder on good grades, shop around for the best vehicle, and minimize your coverage. Find out from your insurance agent if an away at school discount is available and also check into having your teen on a separate policy to reduce premiums.

A driver's license is a rite of passage for most teens. Don't let the high price of insurance get in the way of your teen's new found freedom.
