The law in Germany mandates that you have to help (§323c StGB), and gives you a "Haftungsprivileg" for this situation, making you less liable if you do something wrong. It even goes further, if you suffer damages during giving first aid, you are eligible for compensation. Everything within the appropiate limits, of course.
