Formula One Flags

 All About Flags Used in Formula One Racing

In times past the race marshals used flags to send messages to the drivers. The marshals are positioned around the track each having ten different flags. However today the flags serve as an information source for the spectators.

Modern Formula One racing speeds make it difficult for drivers to be aware of the flags and react in a timely manner. Technological innovations now allow each Formula One racing cockpit to be equipped with a GPS marshalling system that displays the flag color when the driver is passing the relevant track location.

Formula One racing flags follow a pattern. Many of the flags are common to most auto racing events and familiar to the general public. Others are specific to Formula One racing.

The black and white checkered flag is perhaps the best known of all racing flags. The checkered flag indicates the finish of a session or race. During qualifying and practice sessions the flag is waved when the allotted time has elapsed. At the end of a Formula One racing event the checkered flag is waved first at the winner and then at all following cars so that they understand that the race has been completed.

The red flag is also used to indicate the end of a Formula One racing session. The waving of a red flag indicates that the session has ended early, generally as a result of poor track conditions or because of an accident.

The yellow and red striped flag informs drivers of adverse track conditions, such as oil or water on the track. It also may indicate debris on the track.

Marshals may wave either one or two solid yellow flags in Formula One racing. A single yellow flag warns drivers to slow down. Overtaking is not permitted. The yellow flag indicates a problem ahead, often a stranded car. Two yellow flags are waved at once to indicate an even greater danger ahead and that vehicles may be required to stop. A single yellow flag along with the SC sign indicates to drivers that the safety car will be entering the track.

When a slow moving vehicle has entered the track in Formula One racing the marshals wave a white flag, indicating that a reduction in speed is necessary.

The green flag is waved as a message that the track has been cleared and the race may resume full speed.

In Formula One racing the blue flag serves as a warning signal to a driver that a faster car is approaching. The driver is required to allow the faster car to pass. A driver that fails to allow the faster car to pass after passing three blue flags may be penalized.

Formula One racing also uses flags to communicate to drivers regarding their status.

A half black, half white flag is used in conjunction with a sign indicating a specific car number. Formula One racing uses this signal to inform a driver that his behavior is unacceptable. If the behavior continues the driver will be disqualified.

A solid black flag accompanied by a car number sign notifies a driver that he has been disqualified and must return to his pit within the next lap.

The final flag used by Formula One racing marshals is a black flag with an orange circle in the center. This flag is waved to tell a driver that a vehicle mechanical problem has been detected. The driver must return the car to the pit.

Flags allow Formula One racing spectators to easily follow the flow of a Formula One racing event.

Hybrid Cars vs. Conventional Cars

 Today, the question on everybody's mind is what is the difference between a hybrid car and a conventional vehicle? There must be some reason why people are debating about whether hybrid cars are worth it and checking their wallets and savings account to see if they can afford the hybrid car. There must be some reason why other people won't even consider putting out the money for a hybrid car because they feel their conventional car gets them to where they need to go just fine.

Hybrid cars are more expensive than conventional cars. Because hybrid cars have a complex internal design, they can have a pretty hefty price tag. On the other hand, conventional cars, which have gotten more efficient in design as the years have gone on, are quite affordable these days. Because conventional cars have been around for years you can buy a second hand or used conventional car at a good price.  Some people even give these types of cars away. However, since a large percentage of the general population has never owned a hybrid, there aren't many people selling used hybrid cars. Therefore, the average person looking to buy a hybrid would probably have to purchase a new one from a car dealer.

Both a hybrid car and a conventional car can use similar types of batteries. A hybrid and a conventional car can both use lead acid batteries that hold enough energy to power a small motor that's electric. These batteries are what you would call "gear reduced." That means that they can turn over an engine at approximately 300 rpms. Torque is generated to turn over the engine. And the entire process is what ends up starting the engine in the first place.  Even though hybrid car uses a lead-acid battery, its battery that works to recharge the car is constructed differently. This kind of battery is known as a deep cycle battery. And it can be compared to the batteries that are used to power golf carts.

While buying a hybrid car will certainly save money at the pumps if something goes wrong and needs fixed on the hybrid car you can look forward to some pricey repair receipts.  The conventional car until there are more hybrids around will be cheaper to buy and fix.

But the final decision is up to you. There are pros and cons involved with both types of cars. But those who like to try out new things might just consider splurging on a hybrid car.
