Public notices and laws express obligations with the modal verb MUST and MUST NOT.
So what do these public notices mean? Perhaps:
- Police, you must look the other way, I’m growing some medicinal plant life.
- You must not enter this club if you have a heart problem.
- You must not buy a kangaroo for Christmas, they are wild ferocious animals and I can’t stand them!
Now, this is a gentle reminder to my Spanish driving friends about road regulations.
- At a traffic light, you must stop at a red light; a red light does not mean you must accelerate.
- At a roundabout, you must pay attention to lanes and indicate to let everyone know what you are doing.
- Motorbikes must not drive on the pavement.
- You must not deliberately crash into the front or back of a car in order to make a parking space bigger
- You must not put on mascara, check your WhatsUp?-App, nor take your pants off.
