Here's a woolly bear belt for you. Looks like an easy winter! ===[***CDM***]===

Thanks, Cue! Here, in Minnesota, this winter is supposed to be colder than normal with more snowfall than normal.
The penguin will have to do since there aren't any winter emojis yet.

This belt puts you in the driver's seat, Lex! ===[**CDM**]===

And, thanks for the song. One I've always liked.

Thank you: I'll try to keep the truck on the road...

Here are three related clues to cudgel the brain, all three answers needed for the Belt please:

1. Writer glad aeroplane crashed (5,5,3)

2. New party starts to hunt aggressively (5)

3. Navy constantly increasing as 1's 2 said (9)

[These and and six more related clues are also on a new thread Almost a Brit Xword...]

1 direct on the left vccvc vccvc cvv

2 direct on the right cvcvc

3 direct on the right cvcvccvcv

1 has been answered on the other thread

I suspect that 2 may be the trickiest: it is a meaning of the word with which I was unfamiliar - wordplay 4 (party) + 1 (new)

Wordplay for 3 is 1+ 4 + 4

2 starts with R and 3 starts with N

All of these have now been answered on the other thread, so who's going to claim this...?

It should probably be manxman on the basis that he solved the last one

Thank you Kevin

That answer was music to my ears, Sue! ===[**CDM**[===

I was just fiddling around with the words and it practically composed itself. Thank you!

Actors began to get rooked? (7)

Hm - not sure about this - "castled"

Actors are a cast and a rook is a castle but can't explain the "led" unless it's just that the word meaning "rooked" began with "cast"

You got it, mate! "Led" is clued by 'began". ===[**CDM**[===
