Have you had any hypos (low blood sugar episodes) yet? Three important things re hypos and driving
1) you have hypo awareness so that you recognise when a hypo occurs and treat it. You need to not have needed help from others to recover from a daytime hypo.
2) Always do a blood test before you get in the car to drive (and don't if you're too low).
3) Always have sugar (glucose, jelly babies whatever) with you when you drive so you can stop and treat yourself if you feel low,
Number 1 will ensure you keep your license, numbers 2 and 3 will ensure you don't hurt yourself or anyone else when driving. Driving when hypo kills.
