Summer hit. Be prepared for extremely hot summer weather
Most major holidays that significantly affect travel occur during the summer and winter. Extreme heat and extreme cold can become huge factors when traveling by car during the already strenuous holiday driving seasons. When traveling for the Fourth of July or Memorial Day, make sure you have a few bottles of drinking water in your vehicle in case of being stranded in the heat. A gallon of filtered water is also handy, too, in case your vehicle overheats. Get your air conditioning system serviced before making any long trips to ensure that you and your passengers stay comfortable.
