if i am injuried leaving my house prior to getting into my vehicle for work am i covered under workers comp?

The quick answer is, it depends.  Usually commuting injuries are not covered, but there are exceptions.  If you drive to the same fixed work site everyday, you are probably excluded.   However, if you are a traveling employee going to different job sites, on a special mission for your employer (ie being called in to deal with an emergency) or using a company vehicle, it is worth exploring this further as you may be able to make a claim.  These cases are very fact-specific, and the caselaw is continually evolving.  Just this week the Commonwealth Court issued published opinions on corse and scope cases.
