This will depend on the circumstances of the alleged driving pattern and the evidence available to the Prosecutor. Typically, defences to dangerous driving offences include either a defence on the basis of identity (the Prosecutor cannot prove that you were the one driving), or that the driving pattern did not meet the necessary threshold for a dangerous driving conviction; or a combination thereof. 

Not all collisions are the result of dangerous driving. An experienced lawyer will be well-positioned to apply the law to your particular circumstances and to advise you accordingly.
