How can my liscense be revoked/suspended 2 years after my car accident?

I had a accident on June 10th 2014, my car was uninsured but my liscense were only expired/out dated. I went and renewed my liscense and continued to drive with no problems. Had been pulled over several times and liscense handed back to me with warnings to slow down. In july 2016 I was told by an officer my liscense were suspended or revoked.no drugs/ alcohol involved in the accident. and before the accidentfor 30 years I've had a perfect driving record.
