Is it allowed to be on your test for over 90 minutes due to traffic

I just want some views here I failed due to undue hestitation not pulling out of a junction I mean it was manic the traffic was at a stand still over to the other side where I had to be and non stop traffic to my left and anyway 90 minutes later at the test centre I had to do my manuvoure still so there was only one space available very close to the fence but I did it yayyy I was so proud I had an awful morning or was 8.10 and there was a fatal accident at 7.30 unfortunately bless but that's why traffic was at a stand still everywhere but I'm confused as to when I have my next test in 2 weeks time if this happens again do I pull out if I'm sat waiting too long and risk it or do I wait until safe to do so I wad absolutely gutted as I thought I handled the whole situation very well I think she was a bit worried as when we finally got back to the test centre she said right I'm going to have to explain now why we are so late I mean really that was not my fault neither hers

Have you never heard of commas, full stops or paragraphs?
