Answer:
Dawna will likely be charged with No Crime
Step-by-step explanation:
All crime committed breaks the law, but not every violation of the rule of law can be counted as a criminal offence.
Crimes are actions that are prohibited and forbidden by the law and such acts are punishable.
But in this case Dawna has committed no crime (unless proven otherwise) because her behaviour (turning on of windscreen wiper) is in line with the ethics of a driver.
Shell likely avoid being charged with a criminal offence but she'll still be questioned and investigations would be carried out to determine if she has committed any crime or not.
