Summer is here and even with higher gas prices, many drivers will be hitting the road for vacations and weekend getaways.

"Hot weather brings unique challenges," said Ray Palermo, director of public relations for auto insurer Response Insurance. "It can present dangerous conditions for both the vehicle and its occupants." Each summer sees more than 7 million car breakdowns on the road and he suggests that most summer breakdowns can be easily avoided.

Before heading out be sure to check out the basics, including oil, transmission fluid, windshield washer fluid, battery level and strength, tire pressure (including the spare), the cooling system (which should be flushed and refilled at least every two years), belts and hoses and have a well equipped emergency kit and tool box in the trunk. "Drivers need to stay cool as

well," said Palermo. "Our studies have shown that 75 percent of drivers are fearful of encountering road rage and 37 percent said they had personally experienced it in the previous six months."

Don't escalate aggression on the road by responding to it. Stop periodically to refresh, take along moist towelettes and water.

When driving in hot weather it's particularly important to keep an eye on the lights and gauges. If the temperature gauge moves up, turn off the air conditioner and turn on the vehicle's heater to its highest, hottest setting. It will be uncomfortable, but it will help draw some of the heat away from the engine.

If stopped in traffic, put the car in "park" and lightly step on the gas to help circulate coolant. If the temperature light goes on or if the gauge enters the red zone, immediately pull off the road to a safe spot, well away from traffic.

Do not drive any farther, not even to the next exit. Driving with an overheated engine can cause serious damage to the engine.

Do not attempt to remove the radiator cap. The pressurized coolant is extremely hot and will spray out with great force. Do not pour water over the radiator or engine, since a dramatic change in temperature could cause damage. After the engine cools a bit, add a 50-50 mix of coolant and water to the reservoir to bring it up to its proper level.

Summer heat can pose other dangers. Never leave a child or pet in a parked car in the heat. Even an outside temperature in the 80s can quickly bring a car interior to well over 140 degrees. Bring a cellphone for emergency calls, but don't use it while driving. Response's studies have shown that driving distractions have become the No. 1 fear on the road.
