No, it does not depend on ‘how you look at it’. The truck driver did not use a turn signal. Not all truckers are this way, but a great majority of them think they can do whatever they want and everyone else around them should accomodate them because they have a ‘I have the bigger vehicle’ mentality. I understand that they cannot stop on a dime, so if they have a space in front of them on the highway don’t jump right in front of them. Otherwise, they are just like everyone else and should follow the same rules.
