She is unfit to drive and frankly unfit for the modern world. While I might venture to suggest you go and get your own beers, in general it's not the job of her boyfriend to go pandering to her silly hang-ups, it's her job to put her big girl pants on and get things done that need to be done.
In any case, temporary traffic lights are advisory only, it is not a criminal offence to drive through them. That's why they all have big cameras on the top, to dissuade people. Even if it were an offence you would hardly be prosecuted if they were stuck on red, and a queue of other drivers would be your witnesses. Finally, there is always a number displayed that you can call if the lights are stuck. The person on the other end of the phone will authorise you to drive through the lights and send a team to investigate the problem.
