When driving, what can cause you to miss warning signals?

You correctly selected loud music and being distracted during a telephone call. Both can make it harder to notice important warning signals while driving. Loud music can mask sounds like sirens or horns, and distractions from phone conversations can take your attention away from the road. Driving at a low engine speed does not impact your ability to notice warnings. Always keep your focus on driving and keep distractions to a minimum to ensure you notice all signals around you.
